Dancing with the stars! Pharrell Williams got the 2014 Oscars off to a lively start on Sunday, March 2, when he took the stage at L.A.'s Dolby Theatre to perform his Academy Award-nominated song "Happy."
Wearing his now-trademark oversized Vivienne Westwood hat, Williams was joined by a crew of energetic dancers, who leapt around the stage behind him as he sang. Midway through the performance, he descended the stairs and enlisted Best Supporting Actress nominee and 12 Years a Slave star Lupita Nyong'o in an impromptu little boogie. She gamely swirled her hips to the beat before he moved on to two other nominees: August: Osage County's Meryl Streep and American Hustle's Amy Adams.
"Happy" is featured on the Despicable Me 2 soundtrack, as well as on Williams' second studio album, G I R L, due out Monday, March 3. It recently hit No. 1 on the Billboard Hot 100 chart, dethroning Katy Perry's "Dark Horse."
"It's pretty crazy," he told the Associated Press of the song's success. "It's really awesome and I'm still shocked."
