Singer-songwriter-producer Pharrell Williams will perform his Oscar®-nominated song “Happy” at the Oscars®, show producers Craig Zadan and Neil Meron announced today. The Oscars, hosted by Ellen DeGeneres, will air on Sunday, March 2, live on ABC.
“Happy,” which Williams wrote and produced for “Despicable Me 2,” is nominated for Original Song. The three other nominated songs are "Ordinary Love" from "Mandela: Long Walk to Freedom," "Let It Go" from "Frozen" and "The Moon Song" from "Her."
Pharrell Williams has won seven Grammy Awards®, two (in 2004 and 2014) for Producer of the Year. Named Billboard’s Producer of the Decade in 2010, his productions have sold over 100 million copies.

As a solo producer and as part of the prolific producing team The Neptunes, Williams has played a key role in creating a string of hits over more than two decades, including Jay-Z’s "I Just Wanna Love U (Give it 2 Me)," Nelly’s "Hot in Herre," Gwen Stefani’s "Hollaback Girl," Snoop Dogg’s "Drop it Like it's Hot," Britney Spears’ “I’m A Slave 4 U” and Justin Timberlake’s “Like I Love You.”
