Kim Kardashian Takes Cheap Shot At Paris Hilton About Sex Tape

Perhaps Kim Kardashian has never heard the proverb that people who live in glass houses shouldn't throw stones.

On Sunday night's episode of "Keeping Up With the Kardashians," Kim took a cheap shot at former BFF Paris Hilton.

While Kim was helping her mother spy on stepfather Bruce Jenner at a golf course, Kris asked Kim if she remembered to bring the night vision camera, and that's when Kim responded, “No. That was Paris Hilton.”

Of course, Kim was making reference to Hilton's infamous sex tape with Rick Salomon that was shot in night vision in 2003.

Kim really isn't in any place to be making jokes since she has her own sex tape, shot in 2003 with former boyfriend Ray J, which leaked in 2007 and helped her become the celebrity she is today.

Last week, we weren't impressed when Kim's ex and sex tape co-star took his own shot at the reality star, when he turned to Twitter to mock her about their sex tape -- but if Kim is going to take shots at Paris on her show, it's all fair game.
