Anyone who saw David Guetta headline Coachella's Safari Tent on Sunday night (April 12) got an exciting surprise: The Black Eyed Peas joined him onstage to perform "This Is Awesome" and "I Gotta Feeling."

History lesson: Guetta actually collaborated on the Black Eyed Peas mega-hit "I Gotta Feeling," which was released six years ago. This song (and Guetta's work on it) has been credited with breaking electronic music into U.S. radio. Guetta has producing credits on two previous Black Eyed Peas albums: The E.N.D. and The Beginning.

Gutter's November 2014 album Listen, also features collaborations with SiaNicki MinajJohn Legend, Emeli Sandé, Ryan Tedder, Sam Martin and Nico & Vinz.

As for the Black Eyed Peas, hinted back in January that we just might be seeing more music from the group very soon (via Capital FM).
