Actress Mila Kunis and her husband, actor Ashton Kutcher, are at the top of their game professionally, a kind of golden Hollywood power couple. And, up to a point, it's real. But, behind the scenes there are those stories and rumors of strippers, addictions, cheating, a serial killer or two and a "bedroom" life that has peaked and is reportedly on the wane. And we all know what happens when that happens. They met on the set of That '70s Show. Their first on-screen kiss was her first kiss, like ever. Reportedly, they didn't get on all that well back then. Or maybe they did. Who knows. The various versions of their stories sometimes get a little (or a lot) garbled. Is it really a case of Ashton, the serial philanderer, tamed by Mila? Well, it sounds good, doesn't it? But, what's the old line about a leopard and changing spots? Exactly. Here are 15 things Ashton and Mila really don't want you to know.

15. Ashton And The Swedish Make-Up Artist

Back in 2012 when Mila and Ashton were supposedly a "new" couple (more later), some say Ashton ran into blonde and beautiful Swedish make-up artist Linn Massinger, in a California bar, while Mila was in New York. You know the kind of thing. She was blonde and hot and Ashton was a hunk and so their eyes met and, of course, he took her home to his pad in the Hollywood Hills. According to Massinger, he took her by the hand and led her upstairs. Well, you get the point. The only trouble was she was a blabber. Either she sold her story or did it for her 15 of fame (or both), but pretty soon it hit the tabloids in a big way. Seems she talked to The Sun first. The story was nicely timed to coincide with the birth of daughter Wyatt, in 2014. We're sure Mila remained calm, cool and collected. Not. Would I do that kind of thing, he said. Well, in a word, yes.

14. Three's A Crowd: Ashton, Demi And Mila?

OK, the official story is that Mila didn't hook up with Ashton until after his split from Demi Moore in 2012. Some gossips report that Demi thought, my goodness, they got together so fast there must of been stuff going on before. The couple has protested way, way too much that they got together after his split from cougar Demi. But the thing is this: Mila has admitted that before they "dated" in 2012 they had "buddy s*x" together. And she tells the story of attending a 2011 party that Ashton invited her to and staying the night. This was around about the time she dumped long time significant other Macaulay Culkin. Whatever the truth behind the rumors, the fact that Mila is not on Demi's list of BFF goes without saying.

13. She Dumped Macaulay Culkin Just As Her Career Took Off

Macaulay Culkin and Mila Kunis started dating in 2002 when she was a teenager and still only an up and coming TV star on That '70s Show, alongside Ashton Kutcher. She has said that when they first started dating, the Home Alone and Uncle Buck star was so popular that fans would freak out when they saw him. She said you couldn't walk down the street with him without all heck breaking loose. So, was her teenage head turned? Apparently. And they were together for seven or eight years, maybe longer. Then, just as Macaulay's fame was diminishing, Mila made Black Swan. In fact, she won a Best Supporting Actress Oscar for her efforts in that film. So, goodbye Macaulay. Why? Hello Justin. Does she regret it? According to Inquisitr, yes.

12. Kutcher's Ex-Girlfriend

In 2001, Ashton was a 20-something, up and coming star who was dating one Ashley Ellerin. She was hot and blonde and worked part time as a stripper. And she was stabbed to death by an alleged serial killer named Michael Gargiulo. The press dubbed him "The Hollywood Ripper". On the night she died, Kutcher went to her house and knocked and knocked on the door. When she didn't answer, he looked in through a window and saw what he thought was red wine spilled on the floor. Just out of his sight range lay the body of 22-year old Ellerin. And it wasn't wine he saw. It was blood. She had been stabbed 47 times as she showered. Hence Psycho reference. Kutcher may well have to testify at the alleged killer's trial, if and when it ever comes to court. Authorities think Margiulo may have killed as many as ten women.

11. Once A Cheater...

It's a simple fact that tabloids thrive on rumors put out by "sources close to" celebrities. Now, some say that way back when he was still married to Demi Moore, Ashton discussed Demi and his cheating on her with his former That '70s Show co-star Mila. And the whole world knows about his romp in a hot tub with a kiss-and-tell hottie while he was still very much married to Moore. So, Lifeandtylemag led with a sensational headline: "Ashton Kutcher's Cheating Past Could End His Marriage to Mila Kunis". And then went on to tell the world that: "Mila's paranoia has gotten so bad, she's allegedly searching through Ashton's emails and cell phone to ensure there's nothing shady going on." And, even better, the rag went on to tell us of "huge blowouts", before wishing the couple all the happiness in the world. Sure.

10. Those Leaked Pictures

Around about the time she broke up with Macaulay Culkin, Mila made 2011's hugely successful Friends With Benefits. Her "love" interest was heartthrob Justin Timberlake. So, rumors started circulating that the two weren't just enjoying on-screen "benefits", if you get what we mean. Then (supposedly) leaked pictures start appearing. You know the kind of thing: Justin in bed. Then Justin with pink underwear on his head. Mila in the bathtub. While Justin and Mila denied any romance, the New York Daily News, reported on text messages between the non-pair that confirm that the two were "more than... friends with benefits". And what about their public groping-fest? Read on.

9. Being A Mom Has Hit Their Life In The Bedroom

Speaking of "friends with benefits", The Daily Mail has reported that Mila admitted that she and Ashton started as casual s*x buddies. But when? Anyway, after baby daughter Wyatt was born in 2014, she has also gone on record saying she thinks of the baby when she and Ashton are between the sheets, doing stuff. The paper gleefully reported that she "admits being distracted during sex... as she reveals difficulty in switching off from motherhood". In an exchange with talk show host James Corden, Mila admitted to switching into mommy listening mode. "Wait, is the baby crying..." No, that's probably just Ashton tearing up, Corden quipped. Mila blushed. And giggled.

8. Ashton And That Massage Parlor

A week before Christmas 2015, Ashton Kutcher was  reportedly spotted coming out of a "seedy" massage parlor, while, presumably, Kunis and baby Wyatt were elsewhere? Of course, they were elsewhere. Ashton dropped in on the Ancient Therapy Massage Parlour in North Hollywood. It's noted as much for its "extra" services as it is for massages, according to some reports. Words like "ducking out" with his face "nearly unrecognizable" added to the cheating rumors that of course went viral pretty quickly. Some reports pointed to the fact there was no evidence that Kutcher had cheated. But why visit such a seedy joint when there are plenty of up-market, no services on the side, parlors available?  You figure that one out.

7. Kunis The Addict?

Reportedly, Macaulay Culkin is addicted. And Mila reportedly got hooked while she was with him. No, not that kind of addict. She and Macaulay were said to be addicted to World of Warcraft, the game. Like playing all day and all night addicted. Like don't take care of business addicted. Like live forums and reports and totally living the world addicted. She has gone public saying that she cold turkey quit the game because she was so addicted that she did little else. She belonged to several guilds. So, who knows? If you were into WoW, you could have been playing against Macaulay and/or Mila. Her character did look a lot like her...

6. All That Groping With Justin Timberlake

OK. We're at the 2011 MTV movie awards and despite all the pictures, text and on and on, Mila and Justin are saying no, we are not dating. OK, but are you doing "it" between the sheets? You don't have to "date" to do the deed, do you? The rumors just would not go away after their playful, all loved up performances in Friends with Benefits. So to prove they're are just good friends, he gropes her b**bs and she returns the favor by groping his crotch. See, they say. This proves we are just friends. WTF? Maybe we missed something, but they are getting intimate with one another in public and that proves they are not intimate? Do they think we're dumb, or what?

5. Ashton Convicted For Burglary

Ashton Kutcher had a passion for acting, even back in his high school days in Iowa. But things went downhill after his parents divorced. At one point during his senior year, he and his cousin broke into his school at midnight, intending to steal money. It didn't end well. He was arrested as he was leaving, convicted of third-degree burglary and got three years' probation. It nearly ruined his life, as he lost his girlfriend and college scholarships, as well as being shunned by school mates and the community. In the end, he ended up modeling in those Calvin Klein ads and landed a plum role on That '70s Show, alongside 14-year-old Mila Kunis. And more hassles from his childhood, in his troubled twin brother's cheating/restraining order scandal. You can't pick your family, sad to say.

4. From Russia And Miserable

Mila was all of 7 when her Ukrainian parents moved to the States, eventually ending up in California where her engineer dad was forced to drive a cab to make ends meet. It was a strange world for Mila. The first time she saw a black person, she was so scared she burst into tears. She spoke no English and, reportedly, found the transition very tough. Then a bit of drama school landed her an agent and a commercial for (wait for it ) Sparkle Barbie. That was in 1994 when she was 11-years-old. A few years later a 14-year-old Mila was (in effect) lying about her age to get onto That '70s Show. She told them she would be 18 on her birthday, not specifying it was four years away.

3. Time For A Spot In Rehab?

OK, when Tiger Woods got caught with his pants down, he played the "s*x addict" card, a kind of "I can't help it" excuse that did him no good at all. He famously went to SA rehab. Would it not be fun to be a fly on the wall when Tiger came clean? Anyway, back when Ashton was married to cougar Demi Moore, the Chicago Sun Times reported that those "sources close to Moore" were whispering how she feared Kutcher was a s*x addict and "begged" him to get help. Which, being a red-blooded American boy, he flat out refused to do. A lot of Ashton-caught-cheating stories have come and gone since then. Ashton's problem? He reportedly keeps hitting on the kind of bombshells who kiss-and-sell-the-story. Maybe he should take a leaf from Prince Harry's books. Apparently, before Meghan Markle, he almost always dated upper crust girls who wouldn't dare rat him out.

2. Friends With All Those Benefits

Mila has said she didn't "date" Justin Timberlake, but rumor had it they slipped between the sheets together. Just look at those leaked pictures. And what about all that mutual groping? Fast forward to Mila and Ashton. The official story is that they started dating in 2012, after his break-up with then wife Demi Moore. USWeekly reported on Mila's admission to Howard Stern that she and Ashton were "sex buddies" long before they dated. Seems he invited her to a party in 2011 and she ended up staying there all night. "So I went over. Long story short — I didn't leave till the next morning," Kunis reportedly said. Of course, she had to add, it was the first time she had stayed the night with a guy. That was probably to keep mom and dad off her back.

1. Fasten Your Seat Belts. It's Going To Be A Bumpy Ride

Well, it's true that a cheater who cheats on his first wife will almost certainly do more of the same if and when he marries again. Sara Leal, his hot tub hottie talks of being"seduced" by Kutcher. Linn Massinger, the blonde bombshell from Sweden, says Kutcher didn't even mention Mila when they hooked up at his party palace in the Hollywood Hills. And Scott Eastwood has thrown in (for free) that Kutcher probably cheated with Scott's then girlfriend while he was still married to Demi Moore. And then we've got that massage parlor fiasco. So, will it be happily ever after for the Kutchers, or do they need to have divorce lawyers on call? As Kutcher comes up to the dangerous 4-0, it may just be inevitable that the couple is in for one bumpy ride. Sometimes, as a man gets older, his women get younger...
