Carmen Electra was the host with the most on Friday night as she presided over a packed crowd at Eva Longoria Parker's new Las Vegas nightclub, Eve.

Electra's fiancé Rob Patterson, formerly of the rock band KORN, hit the DJ booth and mixed a set while Electra danced and mingled with other celebs including boxing great Floyd Mayweather. Arizona Cardinals quarterback Matt Leinart was also in the house.

Before heading to Eve, Electra and Patterson dined at Longoria Parker's steakhouse Beso, beneath Eve in Crystals at CityCenter.
