‘Just friends’: So, what about THAT kissing photo, Olly and Caroline?

Either they're the biggest trollers the world of celeb romance has ever seen, or they are genuinely planning to get with each other at the X Factor Christmas bash.

Whatever the story is, there's definitely something going on between Olly Murs and Caroline Flack.

The pair, who co-host the TV talent show together, were pictured last night looking like they were milliseconds away from having a proper snog. 

Yes, Caroline did post this photo on her own Instagram and no, it's not a hoax. It seems the pair decided to have some fun in the photobooth at last night's Cosmopolitan Ultimate Women Awards 2015.

Both Caroline and Olly have spoken out about the rumoured romance before, and while they've *kinda* made efforts to deny it, they've also 100% helped to fuel the speculation too.

"We have this innate understanding of one another – we don't fancy each other and yet we don't not fancy each other," said Caroline after the pair appeared to kiss on an episode of The X Factor last month.

"We're not girlfriend and boyfriend, yet we're not totally platonic either."

As for Olly, at last night's awards he insisted he and Ms. Flack were just pals – and he admitted they enjoyed playing mind games with us all.

"It's just stirring the pot really, we know we're best mates – that's all it's going to be," he said.

Say what you will Olly, but those photos say otherwise.
