Camryn has revealed what it is like to go on tour with One Direction.

The US singer has been supporting the British boyband on their European Take Me Home jaunt after previously warming up for them in America.

Speaking to Entertainmentwise, Camryn said that Niall Horan has been getting up to some pranks backstage. She said:

"Niall's definitely scared me a few times. He just terrifies me sometimes. He is quite hyper, but for the most part he's calm, but at the same time he's quite hyper!"

Camryn added that Liam Payne is the "calmest", before saying:

"[It's] all really calm before shows and right before the shows and then everything kind of starts happening and everyone gets excited."
