The stars flocked to the hottest party of the night ... the Vanity Fair post-Oscars party at the Sunset Towers Hotel.

Victoria and David Beckham made their way into the star-studded party. Posh, 37, was wearing a gorgeous white gown from her own collection with a skinny black belt.

Katie Holmes, wearing a strapless chiffon gown by Elie Saab, was escorted into the party by sexy hubby Tom Cruise.

And a blue-haired and single Katy Perry rocked a shimmery Blumarine gown. Yikes ... may be a good time to get that hair back to normal, girlfriend!
