Paris HiltonParis Hilton has insisted that she was just joking when she called former BFF Kim Kardashian’s bum “disgusting” and like “cottage cheese in a big trash bag”.

The socialite made the remarks during a telephone interview with Las Vegas radio station KLUC-FM yesterday when she was asked whether she’d prefer Kim’s bum or Jessica Simpson’s “rack”.

She replied: “I would not want [the ass], that’s gross. It’s disgusting. It reminds me of cottage cheese in a big trash bag.”

She wouldn’t want Jessica’s boobs either because “I like how mine are. I don’t like big boobs, they’re too big.”

But after the interview was over, she quickly backtracked to make it clear that she didn’t mean Kim any offence by the remarks.

She told In Touch magazine: “I was just joking around and I made a stupid joke.”

“I felt really bad afterward, so I contacted Kim and apologized. It was a silly thing to say. Kim’s hot!”

Kim is said to have accepted the apology, saying: “Paris and I have been friends since we were kids and I’m glad she made the effort to say she’s sorry.”
