The Xtra Factor's Olly Murs has revealed that if both he and co-host Caroline Flack are still single by the time they're 40, they might consider tying the knot.

Speaking to London's Metro newspaper, the 'Dance With Me Tonight' heartthrob explained that they have such a great chemistry both on and off-screen that it would make sense to pair up if their love lives don't materialise elsewhere:

"If we get to 40 and we’re both single I’m sure we’ll just tie the knot. Well be like, "Do you know what? Sod it. We get on really well, we may as well just get married". Me and Caroline are best friends, we're BFFs. We get on so well. I hope she finds the right man in her life as I’m sure she wants me to find the right girl."

When asked if he's concerned by the fact that Flack's mobile phone recently went missing, he joked that he can't recall sending her any risque texts that could get either of them into trouble:

"Well…I hope not! I don’t think so. I’m trying to think back! No, I’m not worried about anything that’s on there."
