Joan Rivers 'roasted' in Los Angeles

Joan Rivers was the subject of a number of gags about her plastic surgery and sex life at a roast in Los Angeles, it has emerged.

The 76-year-old star was lambasted by her peers at the Comedy Central event hosted by Kathy Griffin, the New York Post reports.

Comic Greg Giraldo said: "You're like Robo-Cop, you're half-human and nobody's given a s**t about you since 1986.

"You actually have a lot in common with Michael Jackson. You both spent thousands of dollars to look like the Crypt Keeper. You're both more popular now that you're dead."

Jeffrey Ross continued: "Joan had a difficult choice to make, whether to do this roast or be the fifth celebrity to die this month.

"Who's your plastic surgeon? Tim Burton? Oh my God, Kanye's mum had a better plastic surgeon. Look at her, she's a cougar. Freddy Cougar!"

Brad Garrett added: "Joan has f**ked more old Jews than Bernie Madoff."
