Jennifer and Owen dated for a short time in 2008 after filming Marley & Me together.

Sandra Bullock and Matthew Mcconaughey became a couple after starring in A Time To Kill together. Despite the fact they looked SUPER CUTE together with their matching glossy curls, their relationship lasted less than two years.

Before Seal married Heidi Klum and started throwing THE BEST Halloween parties of all time (seriously, if you don't know, check them out), he briefly dated model and 'smize' enthusiast, Tyra Banks.

We don't want to be dramatic, but Kate Moss and Johnny Depp were probably the hottest couple OF ALL TIME.

Seriously, just look at them. That hair! Those cheekbones! PHWOAR!

The couple met in 1994 - when Johnny was 31 and Kate was just 20 - and dated for four years and were reportedly even engaged.

Brace yourselves, ladies, for you're about to witness pictures of dreamboat Jake Gyllenhaal looking TOTALLY besotted with another woman. The woman in question is, of couse, Kirsten Dunst, who he dated from 2002 - 2004.

Look, here he is gently cupping her face as he stares adoringly into her eyes...

And here they are snogging each other's faces off in a doorway. JEALOUS!

Long before he went naked paddle boarding with Katy Perry, British actor Orlando Bloom dated super-chic actress Kate Bosworth.

Wow, these two REALLY looked great together. Just look at them! Cindy Crawford and Richard Gere first met in 1987 when Cindy was just 21, and wed four years later. Sadly their huge 17-year age gap proved fatal, and the couple divorced just four years later in 1995.

Yes, much to everyone's surprise, Ryan Gosling and Sandra Bullock were once a 'thing'. Briefly.

Kim Basinger and Alec Baldwin were married for nine years and have one child - Ireland Baldwin - together. Sadly, their relationship ended in a bitter divorce in 2002.

Long before Blake was ultimate #CoupleGoals with hubby Ryan Reynolds, she made Gossip Girl fans' dreams come true by dating her GG co-star Penn Badgley. Sadly the couple broke everyone's hearts by splitting up three years later, but we think we can all agree it was for the greater good.

Yes, Oscar winning actress Natalie Portman briefly dated the much-maligned musician (and fellow vegan), Moby. Strangely, the only image we could find of them was this one where they're posing with Questlove and Black Thought from The Roots and even more inexplicably, Natalie's holding a cake. GO FIGURE.

Whoopi Goldberg and Ted Danson's relationship may have been short (it only lasted about a year), but it had HUGE ramifications - mainly because Ted was married at the time and his affair with Whoopi resulted in his second divorce. Gulp.

Can we all just take a moment to remember just how great Gwyneth Paltrow and Brad Pitt were together. Look - they even had matching hair! The couple, who were together from 1994 - 1997 met when Gwynnie was just 24, and were even engaged. Talking about the relationship years later, Oscar winner Gwyneth admitted: "I f----- that up, Brad!" REGRETS!

Who do you possibly date if you've just broken up with Brad Pitt? Well, if you're Gwyneth Paltrow, that answer's Ben Affleck. The couple dated on and off till 2000.

Let's take a trip back to 2007, when Sienna Miller had everyone asking, 'WTF does SHE see in HIM?' when she began dating super-scruffy Welsh actor Rhys Ifans (yes, we know he's probably got a great personality, but COME ON!).

Back when Kim Kardashian was BFFs with Paris Hilton and still had most of her real face (circa 2006), she was doing the dirty with Nick Cannon - aka. Mariah Carey's baby daddy.

And look, here they are posing with a topless woman who's carrying a snake. Good times!

Before we all knew her as Betty Draper in Mad Men, January Jones dated Ashton Kutcher. The couple dated from 1998 - 2001, but sadly, despite the fact they look seriously happy in this snap, it turns out Ashton was a bit of a jerk. Talking to GQ in 2009, January admitted: "He was not supportive of my acting... He was like, 'I don't think you're going to be good at this."

Long before he was dark and brooding and Christian Grey, Jamie Dornan was the dark, brooding boyfriend of Kiera Knightley. Lucky girl!

Yes, Jessica Biel (who's now happily to married to Justin Timberlake) used to date Captain America! Sorry, we mean, Chris Evans. Who knew?

Madonna's dating history is long and varied - from legendary artist Jean Michel Basquiat to, er, Vanilla Ice - but let's take a minute to remember that her first husband was none other than Sean Penn. The couple were married from 1985 - 1989, and although they weren't suited in many many ways, they certainly looked great together.

J-Lo has had some hot, and seriously famous, O/H's (hiya Diddy, Marc Anthony, Ben Affleck!), but did you know she briefly dated actor Wesley Snipes in the mid-90s? No, neither did we!

And the award for the cutest celeb couple of all time is... Mila Kunis and Macaulay Culkin. Seriously, just look at them! We. Can't. Cope.

Winona Ryder and Matt Damon met in 1997 after being introduced by Gwyneth Paltrow (who was dating Matt's mate Ben Affleck at the time). The couple became official in 1998, but broke it off just two years later in 2000.

Owen Wilson dated All I Wanna Do singer Sheryl Crow from 1999 - 2001. Here they are having a red carpet snog which Sheryl doesn't look 100% comfortable with. Eek!

Courteney Cox and Michael Keaton dated for an impressive (in Hollywood terms, at least) six years. Following their split in 1995, Courteney said: "It's the most important relationship I've ever had, and I think he's the most wonderful person I've ever met." Awww!

Remember when Jennifer Aniston dated Vince Vaughn? The couple started dating after filming The Break Up together (which was possibly a bad omen) because, as you can see from this snap of them not enjoying each other's company, it wasn't really #CoupleGoals

Does Ryan Reynolds and Alanis Morisette strike anyone else as a bit of an odd coupling? Yes, we know they're both Canadian, but still. Anyway, the couple dated for five long years after meeting at Drew Barrymore's birthday party in 2002 (IMAGINE!), and were even engaged to be married.

Sadly they never made it down the aisle, but they did manage to get in A LOT of PDAs before splitting in 2007.

George Clooney's dated more gorgeous women than we've had hot dinners, but we were particularly into his short-lived fling with Charlie's Angels star Lucy Liu.

Look at these cool kids! Yep, Cameron Diaz and Jared Leto dated from 1999 - 2003 and were reportedly even engaged. We think they looked pretty great together tbh.

Despite the fact that Nicole Kidman and Lenny Kravitz dated for two years (2003 - 2005) and were even engaged, the only photos we could find of the pair was this seriously awkward encounter with Nicole's hubby Keith Urban.

Like, REALLY awkward. Let go of her hand, Lenny!

Yes, that is Robert Downey Jr. And yes, he dated Sarah Jessica Parker - for an incredible seven years in fact! We love this snap of them looking seriously cute and gawky back in 1990!

And here they are at the London premiere of SJP's film LA Story shortly before their split in 1991.

We LOVED Whitney, but she really did have awful taste in men. At the time of her death the legendary singer was dating Ray J (of Kim Kardashian sex tape fame).

Cameron Diaz and Justin Timberlake began dating after meeting at the Nickelodeon Kids' Choice Awards in 2003 (proof that love can strike any time, any place). The couple dated for almost four years, and appeared to spend much of their relationship looking loved-up at sports events. Here they are staring lovingly into each other's eyes at a charity basket ball game...

And here they are having a cheeky snog at a Lakers game. As you do.

Before Brad, Jennifer Aniston dated Tate Cooper- who you'll probably know as Jimmy Cooper, Marissa's hot dad in The O.C.

And finally, who can forget the time that Tom Cruise and Penelope Cruz began dating and everyone REALLY hoped they'd get married and double barrel their names #Mems
