Sex Tape Update: Kim K. Fights Back!

Kim Kardashian wants to set the record straight. When news broke last week that Vivid Entertainment was planning to release a sex tape featuring her and her ex, singer Ray J, conspiracy theories surfaced that she was secretly in on the deal. But when Usmagazine.com caught up with Kardashian at Justin Timberlake's pre-Grammys party Friday night in L.A. she called those rumors "ridiculous." "It's really hurtful to me and my family and, contrary to rumors, it's all happening against my will," Kardashian, 26, tells Usmagazine.com exclusively. "I'm sure any woman can understand what it feels like to be betrayed like this. I'm exploring all my legal options." Kardashian showed her disgust with her ex the next night at the House of Hype party at the Hollywood Roosevelt Hotel, where Kardashian hosted a pre-Grammys bash. Sources tell Us that Ray J arrived at the bash driving a brand-new $300,000 Lambourghini convertible. and when Kardashian learned he had arrived she bolted to hide in a poolside cabana. "She refused to come out until he left," says an Usmagazine.com tattler at the party. "She demanded security remove him, and they did."
