Concerts can be amazing experiences. They can also be nightmares. Jessie J's was more of the latter when she went to one of the stops on the Watch The Throne tour.

“I went with will.i.am to the first Watch The Throne show in London," she explained to The Sun after performing at Radio One's Hackney Weekend yesterday. “I somehow managed to find myself walking into the stage with them all — Will, Kanye, Jay-Z, Kim Kardashian. I was like ‘Wow, what a crew,' then me and my friend got stuck in the toilet. We nipped in to do our make-up and my friend knew the door was broken but locked it anyway and said, ‘Babe I think I’ve broken the door.'"

She was in there for some time before anyone caught wind of it and broke her out.

"They’d been on for one song," she continued. "We could hear them and it got to about 15 minutes and Jay’s security came in and they literally kicked down the whole door.”

We're so glad she's not still in there.
