Christina Aguilera, Eva Longoria, Jack Osbourne, Paris Hilton, Jeremy Piven, Donald Trump, and more celebrate US Weekly's Young Hot Hollywood 20. The list includes Katie Holmes, Kanye West, Rachel McAdams, The Cast of The OC, Lindsay, and Nicole. It doesn't look like they all made it to the event but enjoy the pics of dirty, skanky Christina doing her red lipstick thing. She has so much makeup on that it barely even looks like her.
A bunch more including the worst dressed of the evening - Jaime Pressly
