Ke$ha 'threw up in Paris Hilton's closet'

Ke$ha has revealed that she once threw up in Paris Hilton's closet.

The 'TiK ToK' singer befriended Hilton after she sang backing vocals on the socialite's debut album Paris. However, the pair's camaraderie did not last long.

"We were all dancing, hanging out and I got overexcited and ralphed (threw up) in her closet. I thought it was a bathroom," Ke$ha confessed to Scott Mills on Radio 1.

"That kind of ended the relationship right there. I wouldn't want to be my friend either."
