Lindsay Lets the Girls Loose

Lindsay Lohan's headlights were the highlight of the Us Magazine Hot Hollywood party -- arriving to last night's event in a rather titillating top.

Lindsay's tabqueen frenemy, Paris Hilton, wore a less revealing silkish mini, and showed up with a new sidekick. See you later K-Dash!

"American Idol" host Ryan Seacrest looked snappy in a gold lame (that's la-may!) jacket, while one of the show's guest mentors, Jennifer Lopez -- who was honored as Style Icon of the Year -- breezed in wearing a white pantsuit.

The packed party included popucouple Ashlee Simpson and Pete Wentz -- Ashlee apparently taking eyeliner lessons from Petey -- plus Carmen Electra, Rose McGowan, two former *NSYNCers, the girls from "The Hills," David Arquette and a freshened-from-surgery Gene Simmons.

All this and more in a today's top-heavy edition of Star Catcher.
