Hollywood's Scariest Celebrities

Kevinfeder_guast_11083950_600_1Not everyone in Hollywood is obsessed with Oscar nominations.

Take Wednesday night's big launch party for Xbox's new "Gears of War" game at the Hollywood Forever Cemetery.

First to arrive at the pre-Halloween bash was a Britney-less Kevin Federline, who played the new Xbox game for hours with his posse of punks. No one on the red carpet heard him mention the Oscars once!

K-Fed was so darn busy gaming that he didn't seem to notice all the hot babes at the party. Wanna bet he's like that at home too?

Mr. Spears wore a lot of bling and a sweatshirt that said "Playing with Fire." He spent his time acting like the bad ass Rap Star he isn't.

"Bobby" star Lindsay Lohan -- who may have actually mentioned awards during the night -- showed up in a Gucci frock that she'd worn to her previous engagement that night, the "Gucci on Gucci" book party benefitting the Film Foundation at the Bel Air Hotel.

Wow, the same dress? At two parties ? She must be slipping. The old Lohan never would have been caught dead at two parties in just one frock.

A skeletal Kate Bosworth snuck in the side entrance of the cemetery, which was decorated with bright red skulls and spooky Halloween decor.

Safely inside, bony Bos chatted with La Lohan whom she hadn't seen since they'd hung out together in Paris during Spring '07 Fashion Week.

Just imagine their conversation: "So what designer gave you the most free clothes? Really? Me too!"

Both girls met Epic game creator Cliff Bleszinski and tried to play the game. Bosworth, admittedly not a big gamer, praised the amazing graphics. She told everyone that she'd just gotten her first Xbox 360 a few weeks ago.

Hey, with no steady beau and no meals planned, the girl's got a lot of time to kill.
