On Tuesday, Olympic gold medalist Shaun White celebrated the launch of his new video game, Ubisoft's 'Shaun White Snowboarding,' at Boulevard3 in Los Angeles. The game, available for Xbox 360, Playstation 3 and the Wii, was put to the test by today's hottest celebrities, including Bam Margera, Kat Von D, Kelly Osbourne, Audrina Patridge, Ryan Cabrera, Tila Tequila and more. Check out photos from the party below and pick up the game, which is available in stores now!

Kat Von D's distinct style and all-over ink make her instantly recognizable, but this glam rock tattoo artist is also a fierce entrepreneur, branding herself with TLC's 'L.A. Ink' reality show, makeup line and annual tattoo convention. Last night marked the season premiere of the popular series and TV Squad got the chance to talk with Kat about the shop, the show and her boyfriend, rocker Nikki Sixx.
