Paris Hilton hates Kim Kardashian

Paris Hilton is upset with Kim Kardashian. On Saturday at the House of Hype pre-Grammy party, Paris Hilton reportedly ignored Kardashian.

A source tells, NY Daily News, Paris is mad at her pal Kim because Kardashian lied to her about the sex tape, and denied it ever existed.

An onlooker at the pre-Grammy get-together says Paris "walked right past" Kim at the party, and "ignored her altogether."

Meanwhile, Kim Kardashian tells Usmagazine.com

"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."
