Selena Gomez has quite a history, especially when it comes to dating some of Hollywood’s most notorious bad boys. After all, her fans know everything there is the know about her on-again, off-again relationship with her long time boyfriend, Justin Bieber. Well, it looks like Selena has finally moved on, but it might be with another Justin in her life. And while some people think that Selena has a chance of finding true love, others are worried that she might be getting herself in trouble once again.

Apparently, Selena has reportedly been spending a lot of time with Jennifer Aniston’s soon-to-be ex-husband, Justin Theroux. And yes, if Selena and her new Justin come out as a couple, things will definitely get messy. And that’s not just because Selena and Jennifer Aniston were once very close. It’s because the celebrity world won’t be able to handle seeing Selena without someone who is a Justin, but not a Belieber, if you know what we mean.

With that being said, we’ve got 15 reasons why Selena Gomez might be too good for Justin Theroux. After all, they do come from two totally different worlds.

They Are In Different Leagues

Sure, Selena Gomez and Justin Theroux might be very attracted to one another, but many critics and fans alike would agree that they are in two different leagues. After all, Selena is a pop star with fans who are still elementary school students. Justin, meanwhile, is a Hollywood actor with a hit HBO show and an edgy fashion style with an even edgier attitude to match. Their fans come from two different worlds. It would be hard to see Justin and Selena together, mostly because they have very little in common. At least, that’s what it looks like from the outside!

Life & Style Weekly says, “They've known each other for years through their manager. Initially, they leaned on each other for emotional support after going through messy breakups.”

What’s more, there’s no way on this planet that Jennifer Aniston wouldn’t have anything to say about seeing her ex with her friend Selena! This would leave her absolutely devastated and heartbroken all at once. Cosmopolitan adds, “To think of him with anyone else, especially someone so young and that Jen has a personal relationship with like Selena, is painful for her. Jen doesn’t want to think about it and definitely does not believe it.”

Justin’s Priorities

Now, this has never been confirmed, but many media outlets reported that Justin enjoyed the perks of being “Mr. Jennifer Aniston” for many years in Hollywood. Why? Because being Jennifer Aniston’s husband surely did help his career in the entertainment industry. Before their romance, he was virtually unknown. And because of their marriage, he is now a household name. Justin simply has different priorities compared to Selena. He wants to focus on his work in Hollywood and he’s willing to do just about anything for success and recognition. At the same time, though, Justin has learned that keeping your name in the tabloid headlines sure do help your celebrity status and box office appeal, too. Now, that’s not to say that he would be willing to date Selena for attention but then again, we’ve all seen this happen before, right? Selena is better off getting back with the old Justin than this new one.

One source told Life & Style Weekly, “It’s turned into something more than friendship.”

Despite a 21-year age difference (he’s 46, she’s 25!), says an insider, “Selena and Justin are falling for each other.”

Justin’s Lifestyle

Simply put, Justin Theroux lives a lifestyle that differs greatly than the one Selena Gomez is used to. Even though Selena is a true Texas girl at heart, she spent the majority of her life in sunny Los Angeles. She’s into the beach, the nightlife and everything that Hollywood has to offer under the sun. Justin, meanwhile, is all about the New York City hipster life. He loves to surround himself with artists and people who like to push the envelope, especially when it comes to their craft. A lot of people would agree that Selena doesn’t seem like the kind of girl that would fit in Justin’s crowd. Heck, even his ex-wife Jennifer Aniston didn’t fit in with his friends, and that might be one of the reasons why they separated. Justin’s people aren’t the kind that you would see on a red carpet.

“He’s been hosting and attending a lot of different friendly gatherings,” says a source, according to E! News, adding that the actor “loves New York City and has been spending a lot of time at his apartment readjusting to this new phase of his life.”

Selena Just Wants To Have Fun

Selena Gomez is the kind of girl who just wants to have fun. She’s the life of the party and the girlfriend every girl loves to hang out with. She also loves hanging out with the “in crowd” that love to do all the Hollywood things she does. And that’s mostly party, dance, and have a good time. In other words, Selena doesn’t like to complicate life. Justin, in the meantime, is all about his “revenge” body. Apparently, he’s got a point to prove to Jennifer Aniston and he’s working real hard at it, too.

Justin doesn’t have the time to party, drink and get wasted at Hollywood clubs. He wants to show the world – and apparently his ex-wife too – that he’s a man on a mission. Whatever that mission is, we will soon find out.

“Justin has been hitting the gym hard since the split,” says a source, according to Entertainment Tonight. “He’s been working out for over an hour every day at Gotham Gym. Boxing is a big part of his workout routine.” Theroux has been spotted numerous times in the past few weeks biking to the upscale gym in Manhattan, and the source says it’s because he “loves working out.”

Their Age Gap

Someone might as well say it: Selena Gomez and Justin Theroux’s age gap might eventually be a huge problem, especially if they do end up taking their friendship to the next level. Selena is only 25, in the middle of her prime and loving life. Her career is very important to her but at the same time, she needs to let loose once in awhile. Justin Theroux is 46. It’s hard to say what kind of conversations they are having behind closed doors, given the huge age gap between them. Sure, Selena has seen and done a lot in her life, but is she really mature enough for a guy like Justin?

According to the Huffington Post, Selena put it this way: “The older I've gotten, the more I've learned that I have to open myself up to all opportunities."

"Maybe I'll get burned and not meet the right people, but I won't know until I do it. My mom always told me if I love what I'm doing and I'm having fun then just continue to do it. But if it's not fun for me anymore and I'm miserable, then I'm going to go back to Texas and quit it all, to be honest.”

They Run In Different Circles

Selena Gomez has plenty of best friends that she can count on in Hollywood. One of her closest friends is Taylor Swift. Others include Demi Lovato, Miley Cyrus and even Vanessa Hudgens. Simply put, we don’t see Justin hanging out with any of these women. He and Selena definitely run in different circles.

Justin wants nothing to do with the millennial crowd while Selena is all about it. It’s her world and she’s not about to give up her friends for a man in her life. At least, that’s what her fans are hoping.

Speaking about the Millennial generation, Selena told Harper’s Bazaar, “Mainly I think it’s the freedom to express ourselves and be who we are in an unapologetic way. Thanks to the internet, no matter who you are, you know you’re not alone. Maybe a young boy or girl growing up in the South or wherever is confused and terrified to be who they are because they don’t think it’s right. Now they can see all around them people living free of pain, of hidden agendas, of secrets. I think secrets kill people, I really do. You end up trying to cover up so much of who you are for the sake of your family or whoever, and you think you’re bad for being different. So it’s powerful to see our generation breaking those boundaries and encouraging other people to do the same. There’s a sense of freedom that past generations weren’t able to have.”

Justin Bieber’s Jealousy

Here’s another issue that might be a problem down the road: Justin Bieber’s insecurity. While Selena briefly dated The Weeknd, Justin Bieber made it no secret that he was no fan of the singer, or their romance, for that matter. He even made some public verbal swipes towards The Weeknd in front of the paparazzi. As hard as it is for Justin and Selena to make things work out between one another, he doesn’t like to see her with other men. And he certainly wouldn’t like to see Selena Gomez with someone like Justin Theroux. After all, Justin is no Orlando Bloom. Everyone remembers how the actor took a shot at Justin Bieber at a nightclub and totally missed. Justin Theroux doesn’t miss out on any punches.

Selena once said (according to AZ Quotes), “I believe in second chances, but I don't believe in third or fourth chances. I love talking through things, and I always want to make things work, if I really love someone, but eventually, if they can't fix whatever is wrong, or if they've done something and then they continue to do it, they're probably not going to change for anybody. You can't change a person.”

Selena’s Instability

Let’s face it: Selena Gomez has been in and out of rehab more times than we can count. Now, we won’t go into the reasons why she spent time in rehab, but this might be a problem, should things get serious with her and Justin Theroux.

Selena has a history of ups and downs. And for someone like Justin, he might not have patience for it. He’s a grown man who is still looking to go places, and doesn’t have time to worry about all the silly things in the world.

Plus, Selena is the queen of Instagram. That’s not a title that Justin Theroux would ever want for himself. Selena once told Harper’s Bazaar, “I have a complex relationship with Instagram, to say the least. It has given me a voice amid all the noise of people trying to narrate my life for me and allows me to say, 'Hey, I’m gonna post this, and this is gonna take care of the 1,200 stories that people think are interesting but actually aren’t, and aren’t even true.' So it empowers me in that way because it’s my words and my voice and my truth. The only thing that worries me is how much value people our age place on social media. It’s an incredible platform, but in a lot of ways it’s given young people, myself included, a false representation of what’s important. So, yeah, it’s a complex relationship. Probably one of my most difficult relationships.”

Justin Refuses To Change Or Conform

As a lot of people have noticed by now, Justin Theroux is the kind of guy who won’t change for anyone. He will wear skinny jeans and leather jackets until his last day, no matter how out of date or fashion he might look like. With that being said, there is no way that someone like Justin will ever adapt to Selena’s style or any of the things he likes. He didn’t do it for Jennifer Aniston, and he certainly won’t do it for anyone else. In other words, Justin is all about himself. With everything that Selena has dealt with in her life, she needs someone who is better fitted to her lifestyle.

Speaking about how he used to show for Jennifer Aniston on her birthday, Justin told People Magazine, “It’s always a critical moment, because I have Christmas, her birthday and Valentine’s Day in pretty short order, so I start shopping in November. It’s usually something that is the easiest thing in the world — a snuggie. Or I’ll figure out something like that, something fun. I’ve given up on mass pieces of jewelry or clothes. She’s got all that. It’s usually something like an amazing pair of flip-flops, something she can get cozy with.”

He Might Not Be Over Jennifer

When Justin Theroux and Jennifer Aniston announced that they were separating, a lot of fans and people in the entertainment industry were shocked. After all, they seemed like the perfect match made in heaven. Okay, that might not be totally true, but we wouldn't be surprised if Justin still thinks about Jennifer from time to time. After all, they did share a lot of great memories together. Plus, they are technically still married as their divorce hasn’t been finalized yet. Selena might not want to move that fast with Justin yet. Sure, they probably enjoy each other’s company, but Justin would be better off letting the ink dry on his divorce papers before moving on with a young and beautiful Hollywood star. Everyone needs a little time to breathe in between relationships.

“Jennifer and Justin fell in love hard and fast and yet they were never really suited to one another. He was a New York hipster that loved the alternative lifestyle and Jennifer was living a much more reclusive life when they first started to fall in love,” a source shared with E! News.

“The initial chemistry between them made it easy for them to ignore their differences and incompatibility.”

She Doesn’t Want To Be Associated With A Hollywood Love Triangle

If there is something that Selena doesn’t want to be known as, it’s the “other woman” in someone’s break up. Now, Jennifer Aniston and Justin Theroux’s marriage has been over for months now, but as most people know, this won’t stop the tabloid press from making up their own stories. It would be messy and it’s just something that Selena doesn’t need to deal with right now. A Jennifer, Justin and Selena love triangle made up by the tabloids is the last thing she needs to worry about.

Selena, of course, is not sure herself. She once said (via Brainy Quotes): “I maybe had a first love and had my heart broken, but reflecting on it, I don't think that was love. I think as I'm getting older and having more in-depth relationships, maybe I'll experience it. At the moment, I don't know, exactly, if I've been in love.”

Justin once told People Magazine, “I only ever find myself unhappy if I mistrust my gut. If I’ve learned anything, it’s to do what I want based on my taste. Usually I enjoy myself. It’s simple advice, do what makes you happy. But I’ve been very successful, at least on a happiness level.”

Her Fans Will Never Accept It

Selena Gomez is one celebrity star that has a hard core fan base. After all, she is the Queen of Instagram with millions and millions of fans from all over the world. And as much as she wants to have control of her own life, Selena knows that her fans are watching each and every move she makes. In other words, she can’t disappoint them. She also knows that everyone has very high expectations of her, and that seeing her with Jennifer Aniston’s ex just won’t cut it. Selena’s biggest fans know that she could do better and more importantly, that she deserves better, too.

Selena said this last year (Business of Fashion): “[My mom] said, ‘This entire industry is going to tell you you’re perfect and you’re great, and I’m going to tell you that you’re no better or bigger than anyone. You are the person that you are, and you are very lucky.’ That’s something that’s always been replaying in my head. She just taught me to be kind, and that’s about understanding where I’m at. But it got harder the older I was getting. I was actually more confident when I was younger than I am now.”

The Celebrity World Will Never Accept It

When the tabloid media found out that Brad Pitt moved on from Jennifer Aniston with his new lover Angelina Jolie, the press had a field day with it. Simply put, both the media and Hollywood fans couldn’t forgive Brad Pitt for dumping Jen to be with Angelina. And they also couldn’t accept Angelina as Brad’s new lover.

Now, Selena and Justin aren’t officially a couple, but many critics and fans would agree that the celebrity world just wouldn’t accept them as a couple, either. After all, they still see Jennifer being with Justin while Selena should still be with her ex, the other Justin. Also, Selena knows that there are certain expectations from her. Her fans would be crushed seeing her with her friend’s ex-husband. They also would feel equally horrible, should they ever see Selena get her heartbroken again.

Selena also said (via Business of Fashion), “When I got older, I started to become exposed to the truth behind some stuff and that’s when it flipped a little bit. I realized that, “Oh this is actually really hard, and kind of slimy in certain areas,” and I didn’t realize that certain people wanted certain things from me. My confidence went through a lot with that.”

Jennifer Aniston Will Be Crushed

For the longest time, it was pretty obvious that Selena Gomez looked up to Jennifer Aniston. She was her mentor, her best celebrity friend, and someone who she could trust with her entire heart. In fact, some fans would even say Jennifer acted like Selena’s “Hollywood mother.” With that being said, there’s no doubt in anyone’s minds that Jennifer Aniston would be absolutely crushed seeing Justin Theroux and Selena Gomez on the red carpet together. In some ways, it would be like seeing your daughter date your lover! For Jennifer, it would be the ultimate betrayal, especially since Selena was once so close to her in her life.

She wouldn’t be able to forgive Justin for this and she certainly wouldn’t be able to forgive Selena, either. Plus, if you are a true friend, you don’t go after someone’s sloppy seconds and you don’t go after their ex-husband, either!

Jennifer once put it this way (via Brainy Quotes): “Where would you be without friends? The people to pick you up when you need lifting? We come from homes far from perfect, so you end up almost parent and sibling to your friends - your own chosen family. There's nothing like a really loyal, dependable, good friend. Nothing.”

Selena’s Bad Boy History

Many people will say that Justin – and we mean Justin Bieber – was Selena’s first love in her life. In fact, she’s even hinted it a few times in the past, too. As much as they would break up during their tumultuous time together, they also couldn’t get over each other, either. Selena has a history of dating bad boys like Justin, and it’s something that she’s not ashamed of, either. After all, you don’t think that all of those paparazzi photos are nothing but a pure coincidence, do you?

Justin Bieber told Access Hollywood in 2015, “I don’t know if I’m over it yet. I think that I’m definitely in another place, and I think we’ve definitely went our separate ways. I love her and I want her to be awesome, but there are things that remind me of her. We were so in love. Nothing else mattered. We were all about each other. But when it’s like that and you get your value from that, people will always disappoint you. Your girl or your dude, they’re always going to disappoint you. Your full identity can’t be in that person. My identity was in her. Her identity was in me.”
