Oh dear, what can the matter be...

Kelly Clarkson was so far from keen on meeting her fans - and who can blame her - she locked herself in the toilets. Still, she's got a song out of it:

"It was literally the lowest point I've had in my life... I was just so burned-out.

"I was really struggling at getting somebody out of my life and finding people that really cared.

"The whole song is a prayer. I wrote it in a bathroom of the venue after the show... It was just a really, really bad night."

It explains the chorus, which is someone yelling 'You gonna be in there all night/some of us gotta pee/what, you got the runs?/how long's it take a girl to pee?'
