Paris Hilton Takes Shot at Reality TV Rival Kim Kardashian [VIDEOS]

Paris Hilton and Kim Kardashian have been best friends since childhood, and Kardashian came along for the ride, with the release of her sex tape and reality show. But then the long-time friendship came to an end and both started taking shots at each other.

Paris Hilton rocketed to fame in 2003 with her role in The Simple Life TV series. In November 2003, one week before the release of TV series a four-year-old homemade sex video of Paris Hilton and then-boyfriend Rick Salomon was leaked online and went viral. The sex tape was soon released in DVD format as "1 Night in Paris", despite legal action attempting to stop it.

That sex tape is the major contributing factor to skyrocket Paris Hilton's career and why she had been a "tabloid star. Paris Hilton sued her ex-beau over the release of the tape and won $400,000. She later claimed:

"I never received a dime from (the video). It's just dirty money and (Salomon) should give it all to some charity for the sexually abused or something."

For more than a decade, Paris was the tabloid queen, but the release of Kim's own sex tape and the debut of "Keeping Up With the Kardashians" in 2007 marked the beginning of the end of Hilton's time in power and their friendship. With the release of Us Weekly's first "100% Paris-Free" issue in June2007, Kardashian was ready to take over her throne.

As Kim shot to fame Paris took shots at her, in 2008, Paris said:

"I would not want [Kim's butt] - it's gross! ...It reminds me of cottage cheese inside a big trash bag." According to gawker.com

In February 2009, Kim and Paris were last publicly photographed together during fashion week. Kim and Paris friendship was officially dead by August 2009.The loss of the tabloid crown was apparently a sore spot for Hilton in fact she walked off the set of an interview with "Good Morning America" in 2011 after she was asked if she worried that Kim Kardashian was overshadowing her:

"Do you worry that certain people following in your footsteps like Kim Kardashian are overshadowing you?" Harris asked Paris.

"No, not at all," Hilton said, only to hastily end the interview when asked "Do you worry about your moment having passed?"
