Cheeky hitmaker Olly Murs has revealed that he once came across a celebrity on Chatroulette, but doesn't like to talk about it because no one believes him.

Speaking to Capital FM, the 'Dance With Me Tonight' sensation explained that he was clicking through the website when he stumbled upon Ashton Kutcher:

"I remember seeing him ages and ages ago on chat roulette. 100% - I'm gonna take that to my grave because no one believes me. But one day I went on Chatroulette for a laugh and I flicked through and I saw Ashton Kutcher. He'll probably deny it but I swear it looked the spitting image of him. He was wearing a hoody and trying to be all cool."

Murs also confessed that Kutcher's girlfriend, Mila Kunis, is the sexiest girl in the world and when they met she called him 'Mr. Ex-husband':

"I managed to speak to one of the runners and said you know I'd like to get a picture with Mila and they said 'that's fine, she's waiting anyway. I walked in and she says 'hello Mr. ex-husband'. I was like 'I'll be your ex-husband any day'. I don't mind having a six-month relationship and you can just dump me and divorce me – that would be amazing. I don't know if she's the hottest girl in the world, but she's the sexiest girl in the world."
