H'wood Party Girl

Let's hope Kim Kardashian's dancing skills are better than her video-gaming ones.

Last night, she faced off with celeb blogger Perez Hilton at EA Sports Freestyle Facebreaker Launch Party at the Avalon.

The video game features celebrity avatars who fight each other for bragging rights. And Kim got the full K.O. treatment.

Also going virtual fist to fist last night: Spencer Pratt and Heidi Montag. Heidi's sis, Holly, was also in attendance with none other than Lauren Conrad's ex Doug Reinhardt.

"They were making out," says a source. Holly was overheard telling partygoers that it was her and Doug's first date.

Looks like The Hills are alive with sloppy seconds...or is it thirds?
