Olly Murs had a blast touring with One Direction.
The 'Dance With Me Tonight' hitmaker thinks the boy band are "great guys" and says the cheeky singers - who found fame on 'The X Factor' like Olly - caused chaos behind the scenes while he was supporting them on their US tour.
Olly said: "One afternoon, Niall [Horan] did my sound check for me before I got there and sang all of my songs, which was really funny. On another occasion, Louis [Tomlinson] and Liam [Payne] came running out on stage with Nerf guns and they were hitting me in the back of the head throughout my sound check!
"They're just great guys having fun. They're living while they're young, like the title of their single. That song pretty much sums up exactly what they're all about. From start to finish it was a great vibe and a great atmosphere."
The star also revealed he had no problems dating older women just like cougar-loving band member Harry, 18, and says he understands the fascination with the long-haired teen idol.
Olly laughed: "I already have! I mean, I'm 28, so I've dated my fair share of older girls in the past. I think if you like someone and someone likes you, it doesn't matter what age you are.
"Harry is one of the best looking guys in the world at the moment and I'm sure there are a lot of girls my age who fancy him. He's quite a mature lad too, so the older girls do fancy him."
