The countdown to the Young Hollywood Awards party presented by Diesel was held yesterday at Liberace’s penthouse in Beverly Hills.

Nickelodeon’s Kids’ Choice Awards will air this Saturday at 8pm, and will be hosted by Jack Black. We assume that’s what the Young Hollywood Awards party is celebrating. Nickelodeon is set to offer a new online component to the awards, which will allow users to view the event live from different camera angles on demand from the Nickelodeon website.

Guests pictured at last night’s party include Lindsay Lohan, Nicky Hilton, Haylie Duff, Maggie Grace, Natasha Henstridge, Jesse Metcalfe (who brought a female friend), Ryan Cabrera, Brittany Snow, Deborah Gibson, Stacy Keibler, Shannon Elizabeth, Ben Foster, Frankie Muniz, and Melinda Clarke.
