Zac Efron and HSM sweetheart Vanessa Hudgens were two of the first stars to hit the red carpet, and an elegant Hudgens, dressed in a floor-length Marchesa gown, gushed, "I feel like a young Audrey Hepburn." Efron pulled double-duty at the awards, presenting and performing in a musical number with Hudgens, host Hugh Jackman and Béyonce.

Jennifer Aniston, a surprise presenter, skipped the red carpet, but wowed viewers in a shimmering Valentino Haute Couture gown while announcing the animation awards with Jack Black. The Marley & Me star cozied up to beau John Mayer during the ceremony, about a dozen rows behind Brad Pitt and Angelina Jolie.
Best Supporting Actor nominee Josh Brolin and wife Diane Lane kept their Oscar outfits classic in coordinating black. The Milk star and Lane, dressed in Dolce & Gabbana, later snuggled and stole kisses at the Vanity Fair bash.
Super-couple Pitt and Jolie, both nominated for leading roles in The Curious Case of Benjamin Button and Changeling respectively, stunned on the red carpet, and joked with PEOPLE about it being date night. Pitt looked dapper in a Tom Ford tuxedo, while Jolie dazzled in an Elie Saab couture gown and 180 carats of emeralds.
