In a rumble of reality-show divas, Shanna Moakler and Kim Kardashian had a screaming catfight at Carmen Electra's party at the DKNY Jeans Beach House in Malibu Sunday night.

Moakler, the former Miss USA and co-star of MTV's "Meet the Barkers," threw a drink in the face of Kardashian, star of E!'s "Keeping Up With the Kardashians," and yelled "Whore!" at her.

The bootylicious daughter of late O.J. Simpson lawyer Robert Kardashian once modeled for Famous Stars and Straps, the clothing line of Moakler's ex-husband, rock drummer Travis Barker. But according to Shanna, Kim wanted more from Barker than modeling work.

"She was sending him text messages and e-mails, and this was when Travis and I were working on [staying together]," Moakler told Page Six. "When it happened, I asked her, 'What are these e-mails?' She had no answers for me. She was blatantly disrespectful."

Kardashian retaliated on Monday by strolling around in a T-shirt from Barker's line in front of the paparazzi. "It was in the poorest of taste," said Moakler.

Kardashian posted the following on her blog: "I just want to set the record straight . . . I only had a professional relationship with Travis. It was immature of me to wear [the shirt] out the other day. I just wasn't thinking."
