While comedienne Ellen DeGeneres kicked off the festivities at the 2014 Oscars, Pharrell Williams got things started in the music division with his performance of the infectious "Happy" from 'Despicable Me 2.' Watch his performance online right now.

Pharrell and his giant Grammy's hat were joined by a crowd of dancers on the 2014 Oscars stage for "Happy," before the rapper did us one better and stalked the front role of celebs to see if any were in the partying mood. And some were!

Lupita Nyong'o, nominated for Best Supporting Actress, got up in her Cinderella-inspired dress to dance alongside the performer, and even Meryl Streep had to give us a good shimmy. (Yes, Streep shimmied).

Amy Adams was the last audience member to show off a few seconds of rhythm, but when Pharrell returned to the stage, Jamie Foxx and his daughter, Corinne Foxx, joined him to bust a few moves.

The 2014 Oscars was broadcast live on Sunday, March 2 on ABC, as hosted by Ellen DeGeneres. Watch Pharrell's full performance of "Happy" in the clip above.
