It’s hard to be in a monogamous relationship in Hollywood. Yes, the couple is committed to one another and yes, no one is technically apart of their relationship but there is a third person— the media. Some of the longest and best relationships involving two celebrities are the ones that the media can never truly get a hold of. A lot of people believe that relationships in Hollywood don’t last for a number of reasons; too much temptation and extremely busy work schedules are two of the most common causes. But apparently, what many people believe is actually wrong, there are a large number of relationships in Hollywood that are not only thriving but able to keep the third wheel, a.k.a. the media, out of it.

Even when lies are being spread and gossip is being whispered, their relationships are beating the odds and then some. We figured the trick to having a great, long relationship like the ones on this list is to be super low-key. Not only have they managed to keep people out of their business, but they have also managed to be in relationships that seem to be going in a great direction. The fact that these couples are able to be so hush-hush about their relationships remains a mystery to us. However, it doesn't mean that we will stop being obsessed with how they make it work and what goes on behind closed doors.

Britney Spears & Sam Asghari

No one even knew that Britney Spears had a new boo. She was always seen out and about with her boys but one day, she was seen out with a “mysterious man." The media quickly found out that his name is Sam Asghari and that he is an aspiring actor and model. Spears sure knows how to pick em’, the last few men in her life weren’t the greatest. However, this time around, she seems to be doing something different, she is no longer an open book about her relationships. She is keeping everything under wraps and even when she and he are seen out on the town, she makes sure to keep her lips shut. The most they get is a smile from her and him. Not much is known about how long they have been dating and just where they're at in their relationship and it will probably stay that way.

Catherine Zeta-Jones & Michael Douglas

Catherine Zeta-Jones & Michael Douglas have been married for 20 years and that is basically all we know about their relationship. The couple doesn’t talk much about one another besides the PR-friendly statements like how in love they are, and how they have managed to make it work all these years. However, once during an interview with Good Housekeeping, Jones expressed that marriage is hard work and that it is something that needs constant upkeep. But as much as she revealed, fans still don’t know the extent of their relationship. They are so low-key that fans rarely see them together unless it is a red carpet event. That could also be because Douglas is much older than Jones and probably has less interest in going out for a day of shopping.

Sarah Jessica Parker & Matthew Broderick

Sarah Jessica Parker and Matthew Broderick are really the ideal couple goals. They have been together for 27 years and show no signs of slowing down. They have three kids and parents of even one kid know how stressful it can be. Juggling marriage and kids is no easy feat and this couple has successfully done that for a majority of their marriage. Broderick once told Entertainment Tonight that the secret to a successful marriage is to never go to bed mad. They probably also never talk to the media. No one knows much about the inner working of this couple and to be honest, if SJP wasn’t so popular, we would all totally forget that she is married to Broderick. This couple just seems to blend into the crowd.

Christina Hendricks & Geoffrey Arend

Christina Hendricks is gorgeous, and everyone was shocked when they saw that she is married to Geoffrey Arend. The couple hasn’t been married for as long as some of the other couples on this list, but be sure they won't give anyone the opportunity to talk smack about their relationship. They are rarely seen together, so much so that people forget that they even know one another. If we saw them on the street, they could blend in just like a normal couple, not like a couple that occasionally walks a red carpet or two every few months. This might be one of the most discreet couples on this list. Seriously, when you think about it, when do you ever see this couple do any interviews where they willingly give information about one another? They are really trying hard to keep their relationship their own.

Sacha Baron Cohen & Isla Fisher

16 years is a long time to be with someone, especially because this couple is so mismatched (well on the outside looking in at least). Isla Fisher has proven to be a bit more open with their relationship than Sacha Baron Cohen. She has described their relationship as far from ordinary, mostly because Cohen has a twisted sense of humor that often lands him in much trouble. She is quite protective of her family, which is normal for someone who has a job as public as they do. When Fisher does talk about her husband and her family it’s usually focused on his escapades on film sets, stories that would most likely get out because it’s something happening in the public eye. She is sure to keep what happens in their home private.

Adam Brody & Leighton Meester

Adam Brody and Leighton Meester have a relationship that no one really saw coming. They were both teen actors in The OC and Gossip Girl and later went on to star in an independent film together. The couple went out for a time but broke up then all of sudden without anyone noticing they got back together again and were in a full-blown relationship. Then just like that, they got married, then again, poof! A child is born. They aren’t really popular anymore but when people do see them they instantly know who they are and where they know them from. What’s crazy is it seems like this couple never leaves their house we don’t know anything about them. They aren’t very present on social media and it’s almost as if their relationship is just flat out off topic. Meester had a rough time growing up so she could just be extremely protective.

Jason Momoa & Lisa Bonet

Jason Momoa and Lisa Bonet are the cutest couples in Hollywood right now. Their blended family is everything and on top of them being relationship goals, they know how to keep their love to each other. You only know what they want you to know and believe us, the paparazzi have tried very hard to get into the inner workings of this relationship. They are always snapped together when they are in public and fans fawn over how ridiculously cute their kids are. But this couple is a powerhouse and if they broke up, fans probably wouldn’t find out until months down the road because Bonet is so chill. She even still hangs with her ex-husband and baby daddy, Lenny Kravitz. Don’t expect to ever know what these two have going on unless they make some kind of formal announcement about it.

Alicia Keys & Swizz Beatz

The most we know about Swizz Beatz and Alicia Keys' relationship is that it started out as a scandal and ended up as true love. Besides the initial scandal, this couple is silent in regards to what happens when they lay their heads on their pillows at night. Don’t get us wrong, many publications have tried to pry and have gone as far as to write false news stories about the couple but these two just aren’t budging. Like Jay Z and Beyonce, they don’t feel the need to ever come out and justify anything about their relationship. They make the rounds together on red carpets and support one another at respective events. But besides that, this couple isn’t giving you anymore. Can you blame them? They were flayed in the tabloids when he left his wife for Alicia. They don’t want the bad press.

Felicity Huffman & William H. Macy

36 YEARS— that has to be some kind of record in Hollywood. To think they have been married before they had outstanding Emmy and Academy Award-nominated careers has to be one of the secrets to their marriage. The idea that essentially everyone knows they are married, and yet, no one knows much about their personal lives is astonishing. To be in this business for as long as they have been individually and to be able to be married and work in Hollywood is impressive. Then, they top it off by having kids and legit just living a normal life. It’s as if they aren’t celebrities and no one is dying to pry into their relationship. When they want to they can get candid about their relationship, but they hold all the cards. No one has the opportunity to print anything heinous about their relationship.

Ellen De Genres And Portia de Rossi

After 14 years together, this couple still seems as strong as ever. Their relationship hasn’t been without tabloid drama though. Every few months, there is a new story on the front pages of In Touch, Us Weekly, or the homepage of Daily Mail talking about why the couple is ready to call it quits. If we followed all those stories, they would have broken up and gotten back together on a daily basis. No matter what, they have always stayed mum on what their relationship is like behind closed doors. While they will share a few tidbits here and there, they mostly just share the general information. They reinforce how happy they are and how not true those stories are. We will probably never know what their relationship is like, but it looks like they have fun together.

Seth Rogen & Lauren Miller

When Seth Rogen announced that he got married, the entire comedy world probably gasped. He had never spoken of a relationship before, in fact, he never even spoke about dating anyone seriously. How could he have known this woman for 14 long years and basically keep her a secret? Your guess is as good as ours but even now that the secrets out of the bag, we are still waiting to hear something, anything about his wife, Lauren Miller. The most we can muster up is that they co-found a charity together called Hilarity For Charity that focuses on Alzheimer disease. Also, once he told Entertainment Tonight that the secret to making a Hollywood marriage last is watching a lot of television, which we totally agree with.

Harrison Ford & Calista Flockhart

We don’t know about you guys, but we completely forgot that Calista Flockhart and Harrison Ford were a thing. For 16 years, this couple has been flying under the radar. How they do it we may never know but even when it comes to awards season, they don’t always walk the red carpet together or come to the show at all. To be honest, the way that Ford acts, we would have never known he was in a relationship let alone for THAT long. His pierced ear and schoolboy smile it always seems like he is charming someone. One of the only times that Ford has talked about he and Flockhart’s relationship was way back in 2003 when he told Hello! magazine that he was in love. They even got married in 2009, managing to keep even that secret for a while. This couple is crafty.

Anna Kournikova & Enrique Iglesias

We honestly thought that Anna Kournikova and Enrique Iglesias broke up until they announced that she welcomed twins in 2017. We know that they dated at one point, but it seemed as though their relationship went south. Apparently, a break up never happened and the couple is just so sneaky that they were able to fool everyone into forgetting that they are a thing. Despite how close they are and even starting a family together, the couple is not married. The couple is so tight-lipped that fans will probably never know how far they plunged into their relationship; common law or marriage. There have been a few incidents where they were seen supporting one another at public outings but even then they didn’t act like they are together. They are so darn elusive but thanks to those twins being born, at least we can confirm that they are in a relationship.

Jessica Biel & Justin Timberlake

Jessica Biel and Justin Timberlake have been together for 11 years and the worst thing we have ever heard about their relationship was that Biel was on the verge of leaving Timberlake amidst cheating rumors. However, that rumor pops up at least once a year and the couple always prove everyone wrong by showing up to an event together looking more in love than they did the last time we saw them. The couple never confronts any rumors, they allow their love to speak for itself. The fact that they don’t need to feel the need to justify what is happening in the privacy of their home speaks volumes. Even when they were dating, no one truly ever knew what was going on in their relationship. It was all speculation with no real evidence.

Channing Tatum & Jenna Dewan-Tatum

13 years for a young couple that’s pretty crazy. Channing Tatum is no doubt a bigger star than his wife Jenna Dewan-Tatum usually with a situation like that one half of the relationship feels less than. Jenna, however, comes off as the biggest supporter of her man and it looks like there is no one who can ever tell her anything to turn her back on him. They are very quiet about their private lives which is both good and bad, they could be having problems or they could just be that protective of their love. They also have a small child and maybe they don’t want her to see any negative things written about them and their relationship. Truthfully, they were friends before they were lovers so, even if they broke up, they would still be super protective of one another and whatever relationship they have after their break up.
