Kelly Osbourne says that she was so nervous while performing onstage in Chicago as Mama Morton, she threw up in her mouth.

'I threw up in my mouth. I thought, 'What am I going to do? There's no bin here'. So I had to actually swallow it and then through the whole first scene all I could think was, 'I hope Annette [who plays Velma] can't smell my throw-up breath'. I was so scared.'

Ugh. I think it would've been a better show if she just threw up on the stage. Now that's entertainment, folks.
