Coachella 2014 rumors of Andre 3000 and Big Boi reuniting for the music and arts festival were indeed true, with the Outkast duo set to headline Coachella 2014 on April 11 and 18.

Festival organizers teased eager fans with a tweet of the event's lineup on Wednesday evening, along with a "Hey Ya" reference, "share it like a polaroid picture."

Outkast will be joined by Muse who will be anchoring the Saturday night show, and Arcade Fire as the closer for both weekends.

The announcement of rock vigilantes-turned-legends Motorhead participation in Coachella 2014 came as a surprise to many, the video of the hard rock band posted on the Coachella website sparking interest nationwide.

The music and arts fest will also feature newcomers to the music scene such as Lorde, HAIM and Disclosure.

Coachella Valley Music and Arts Festival, now on its 16th run, is a major annual concert held in Palm Springs, Calif. April each year. It's become so popular that ticketing for Coachella 2014 started on May 2013 and the organizers' official tweet of the lineup on Wednesday caused Coachella.com to crash within minutes.
