If there's one person who probably shouldn't make a sex tape joke, it's Kim Kardashian. But that didn't stop her from making one on last night's episode of her reality show.

On Sunday's "Keeping Up with the Kardashians," Kim and mom Kris Jenner went on a mission to spy on Bruce Jenner during a golf game with former supermodel Angie Everhart.

When they got to the golf course, Kris asked her daughter “Do you have a night vision camera?”

"No," Kim shot back, "That was Paris Hilton."

Of course, Kim is referencing Hilton's famous sex tape with ex-boyfriend Rick Salomon.

While funny, Kardashian is hardly one to throw stones -- as she owes a great deal of her own fame to the video she has with her ex, Ray J.

Kim recently talked to Oprah Winfrey about the tape -- and calls it one of her biggest regrets.

"That’s pretty much how I was introduced to the world. It was a negative way, so I felt like I really had to work ten times harder to get people to see the real me," she said at the time.

"I'm definitely not grateful for that experience," she added. "I would say if I had one regret, that would be it. If I were to do it again, obviously I wouldn’t do it again."
