Paris Hilton is backtracking comments she made about ex-BFF Kim Kardashian’s signature badunkadunk on a Las Vegas radio on April 14th.

“I would not want [Kim's butt] – it’s gross! It reminds me of cottage cheese inside a big trash bag,” the petite Paris retorted during a call-in appearance in Sin City.

Paris now claims “She was only joking,” telling In Touch Weekly:

“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 accepts Paris’ apology: “Paris and I have been friends since we were kids and I’m glad she made the effort to say she’s sorry.”
