Oscars 2014: Pharrell, Lady Gaga, Will Smith, Rita Ora, Paula Patton, & Kelly Rowland

Hollywood celebrated its biggest night at the 86th Annual Academy Awards at the Dolby Theatre on Sunday. Before the golden statues were handed out, the stars paraded up and down the red carpet.

Always the trendsetter, “Happy” hitmaker Pharrell Williams showed off his one-of-a-kind style in Lanvin tuxedo shorts as he arrived with his wife Helen Lasichanh. He changed into his famous Vivienne Westwood “Mountain” hat and red adidas sneakers for his dance-heavy performance.

Lady Gaga donned an elegant Atelier Versace gown to her first Oscars, while veterans Will Smith and Jada Pinkett Smith rubbed shoulders with fellow couple John Legend and Chrissy Teigen.

Following the awards, the stars flocked to the exclusive Vanity Fair after-party in West Hollywood. The most coveted ticket of the night, the exclusive soirée drew a who’s who crowd of A-listers.

Gaga arrived with her blonde date, Donatella Versace, and mingled with Rick Rubin and Stevie Nicks. “Fifty Shades of Grey” star Rita Ora chatted up Steven Tyler, and LL Cool J and his wife Simone snacked on In-N-Out Burger.

Despite her recent breakup with Robin Thicke, Paula Patton was all smiles as she stepped out solo, while her estranged husband was on tour trying to win her back.

Over at the Elton John AIDS Foundation Oscar Viewing Party, Kelly Rowland held court with Britney Spears, Kim Kardashian, and Skylar Grey, while Ed Sheeran dueted with Elton on “Candle in the Wind.”
