Simon Cowell & Carmen Electra...

 

Sitting in a tree. N-E-C-K-I-N-G (a-l-l-e-g-e-d-l-y).

A US source, probably dressed as a ninja says of Carm-on / Colectra: "They were really into each other. At one point, they were talking real close, and he leaned in and kissed her. They started making out".

Man alive.

Nicole Scherzinger & Chris Brown!?

 

Yup, well, according to TMZ they 'got close in a club'. Though it may just have been a reaaaally small club. Nicole has since denied any romance. Still, it was SHOCKING for a second there...

Russell Brand & Geri Halliwell

 

Now that it's over, the brief Spice Girl /funnyman fling seems like a distant dream slash nightmare, depending on your stance.

Ashton Kutcher & January Jones

 

... Before Mila Kunis, and Demi Moore, Ashton dated Mad Men woman and very talented actress January Jones for three years, up until 2001.

She accused him of: “Not [being] supportive of my acting. He was like, 'I don't think you're going to be good at this’. So—f*** you! He only has nice things to say now—if anything, I should thank him. Because the minute you tell me I can’t do something, that’s when I’m most motivated.” Err, okay. Let's move on...

JT & Fergie

 

Yup. Back in 1996, Justin Timberlake and Fergie made sweet sweet music together, whilst possibly lying down, with a synthesizer.

"It wasn't a long-term serious relationship, so there's no bad blood," says Fergie. "He was 16 and I was 23…It was before he got real heavy with Britney."

NAOMI CAMPBELL & LEO!?

 

Aka Naomi Di Campbellrio, or, um, Naordo? Never mind. Let's move on, they did.

Rihanna... with who?

 

Shia Laboeuf. Yup. It happened.

Shia admitted that he hooked up with Rihanna in 2007: “It never got beyond one date. The spark wasn’t there. We weren’t passionate about each other in that way, so we remain friends." NO CHEMISTRY? WITH RIHANNA? Liar LaBoeuf more like. We joke Shia - WE JOKE.

Brad Pitt & Sinitta

 

If these two had lasted we could have had a celeb coupling called Pinitta in the world. It's probably best it didn't.

Sandra Bullock & Ryan Gosling

 

If Ryan Gosling had to be with anyone, anyone, other than heatworld (or you) then we'd like it to be Sandra Bullock. You know, her or current love interest Eva Mendes, obvs.

These two dated waay back. We wish we remembered those days. We don't.

Moby... misses WHICH celebrity ex?*

 

You'll NEVER guess this one, unless you know it already. In which case, you probably will. Give yourself a self high-five, before clicking on the arrow above for the big reveal...

*He may not miss her, this sign is a political statement, PS.

NATALIE PORTMAN!?

 

AND MOBY!? Yes, yes it's true. Because Moby says so:

In 2008 Moby revealed that he once dated the now married mother-of-one, Natalie Portman: "I guess in some people's eyes, nerds might be mildly sexy - and, as a nerd, I'm certainly happy to enjoy some of the effects of that. But as far as the very brief affair that I had with Natalie, it's made me a target of a lot of nerd wrath. You don't date Luke Skywalker's mom and not have them hate your guts." Err, okay. Let's move on...

S Diddy? P Miller?

 

Did Diddy and Sienna Miller hook up in Ibiza? The twosome spend a summer partying in Ibiza and were even spotted holding hands (someone alert the elders etc) BUT they issued statements denying any romance... after P Diddy's long-term girlfriend Kim Porter was snapped looking a bit cross. Awks.

Colin & Britney

 

Ahh Colin and Britney, remember them!? After Britney politely ignored rumours that she and Colin Farrell were involved, the actor sent her a T-shirt which read: “I slept with Colin Farrell and all I got was this lousy t-shirt”. HE'S A FUNNY, FUNNY MAN!

Robbie Williams & Cameron Diaz

 

It was the summer of 2003, the sun blazed high above California, the waves crumbled on to the beach in Santa Monica... WHERE ROBBIE WILLIAMS AND CAMERON DIAZ WERE SPOTTED KISSING AND HOLDING HANDS IN THE SURF. Sexy.

Robbie is believed to have taken Cam' go-karting in Berlin, the romantic devil (who's happily married with a baby now, obvs).

Tyra Banks and... guess who!?

 

Will Smith. Sorry, the excitement was killing us. We don't get out much, clearly.

Will was seeing Tyra for a year, after she appeared in The Fresh Prince of Bel-Air in the early 90s.  Then he began dating now-wife Jada Pinkett and the rest, as they say, is history. And Men In Black films.

George Clooney & Lisa Snowdon

 

Yup, we forgot this one, remembered, then found it as funny as Lisa apparently did. Mmm George Swoon-don.
