Kelly Osbourne Shows Off Her Model Fiance, Luke Worrall, 20 (PHOTOS)

Kelly Osbourne attended an Us Weekly party with her model fiance Luke Worrall, 20, in LA Thursday night.

Kelly, 25, admitted in the April issue of British Elle that she had been terrified the first time she had sober sex with Luke, after kicking drugs and alcohol with his help.

"I was like, Oh God, he must be looking at my big, fat, white arse and my stretch marks and my tits that look like a sad face," she said.
