"Together we can inspire this generation to work to what's really important," Gomez said at the event.
The Australian star was a winner in more ways than way on Oscar night. The best actress winner said her beaded Giorgio Armani gown was heavy, but her look was light and airy as she graced the red carpet.
The “12 Years a Slave” star was a winner before she even set foot inside the Dolby Theatre, wowing on the red carpet in a stunning powder blue Prada gown. She followed up with an equally elegant Miu Miu number at the Vanity Fair party.
The Oscar winner wowed in a black Dior dress with a plunging neckline and her signature cropped hair. She opted for another noteworthy black number at the Fame and Philanthropy party.
Though she went home empty-handed, the “American Hustle” actress was a red carpet winner in a navy blue strapless Gucci gown. The lead actress nominee said she wore her hair up due to the rainy weather forecast. Adams' custom Carolina Herrera after party dress was also a fashion victory as she dazzled in the flowy white frock.
Like fellow best actress nominee Amy Adams, Bullock also chose a navy number and stunned in her strapless Alexander McQueen gown and side swept waves.
Wilde dressed her baby bump in an elegant black Valentino gown as she and fiancée Jason Sudeikis walked the red carpet.
The proud wife of best actor winner Matthew McConaughey was a vision in pink in her Gabriela Cadena gown.
The actress proved you don't have to be nominated to come out a winner and channeled old Hollywood glamour in her low-cut Atelier Versace gown.
While her elegant updo was a promising start, the Oscar winner missed the mark in one-shoulder pale pink Giambattista Valli Haute Couture silk gown. She let her down (literally) and changed into a classic black number, complete with a thigh-high slit, for the Vanity Fair party.
Roberts' black lace Givenchy peplum number missed the mark on the red carpet, especially given her best dressed-worthy looks at past Oscars. Even though the dress wasn't a hit, her megawatt smile never fails to impress.
Known for her outrageous fashion choices, Gaga's Oscars look was decidedly boring as she hit the red carpet in an embellished strapless Versace dress and then opted for a similar look for the Vanity Fair party.
While her hubby Chris Hemsworth looked dapper in a David August tuxedo and shirt, Pataky fell victim to the challenge of dressing her baby bump (the couple are expecting twins) in an unflattering beaded Elie Saab gown.
Clad in a J Mendel frock, the “Pitch Perfect” star tried to hit too many notes by flashing some leg and showing off her midriff under the see-through lace. The faux one-shoulder look was just a bit too much.
Woodard's navy blue Badgley Mischka dress had a lot going on top and was an unflattering style for the “12 Years a Slave” actress. The embellishments drew attention to the top, but the rest of the gown was rather plain.
The wife of host Ellen DeGeneres wore an underwhelming ultra-sheer white halter gown by designer Naeem Khan on the red carpet.
Mrs. John Legend's Monique Lhuillier ball gown was a classic silhouette but a faux pas in terms of its boring floral pattern. However, the sheer black dress she changed into to watch her husband perform at the Governor's Ball dress was a risk worth taking.
Blue wasn't the most fashionable color for 67 year-old Minnelli, who topped off her satin pants and off-the-shoulder top with a blue streak in her hair. Her cobalt look caused quite the Twitter reaction when she hit the red carpet.
