I'm a choir girl gone horribly, desperately wrong.

I'd gone from being this art student messing about with music to this girl with a record deal, magazine front covers and all this hype. In many ways, it was everything I ever wanted, but when it happened all I felt was total, paralysing fear.

Bono told me how to dance in high heels and he also told me about U2's Glastonbury performance and how everything that could have possibly gone wrong went wrong, including him ripping his trousers on stage. I think he was lunging and his trousers ripped! He was telling me how he had to find a new way of performing that didn't involve moving.

I got to live out my 11-year-old fantasies - I got to go on stage with Green Day. Billie Joe called my name from the stage. 'Dookie' was the first album I ever bought. I covered the whole of 'Nimrod' and he'd heard it. That was like the 11-year-old girl dreamed.

It just all went horribly wrong for me on the front nine. I fought back well but it was not enough in the end.

Look, if Givenchy is going to lend you a dress, I'm not going to turn it down. I would wear that dress to just go out and buy a pint of milk if they would lend it to me.
