Celebrities at Vanity Fair Oscars Party 2013 | Pictures

The Vanity Fair Oscars party took place at the Sunset Tower in LA last night. The bash is one of the most exclusive events of the evening and always brings out an A-list guest list. Ben Affleck, Jennifer Lawrence, and Anne Hathaway all dropped by the event after picking up their Oscars at the big show. Jennifer changed out of her strapless Dior gown and into a slinky Calvin Klein frock, while Anne opted to switch into a blue Saint Laurent number after her best supporting actress win. Anne even had a cute run-in with friend Sarah Silverman, whom she gave a hand-kiss to on the red carpet. Earlier in the evening, Miranda Kerr and Orlando Bloom were photo-bombed upon arrival by Jesse Tyler Ferguson, and Reese Witherspoon left the Oscars to make an appearance at the party. Bono brought daughter Eve Hewson, and Gerard Butler buddied up with Jason Statham.

The Vanity Fair bash isn't the only post-Oscars event that went on last night. Elton John held a star-studded viewing party for his AIDS Foundation, and the Governors Ball was another stop on the A-list's party-hopping trail.
