Listen to Outkast on iHeartRadio

OutKast's Andre 3000 and Big Boi may be ready to take the stage together again. 

A source tells that the pair have had "some conversations" about reuniting on stage at next year's Coachella Valley Music and Arts Festival in Indio, California. 

However, another source claims the talks are further along and that it's "all systems go" for an Outkast reunion. 

If Outkast does end their six year hiatus at Coachella, sources say it could be the start of a tour that would take the duo to several music festivals in 2014.  

In the 15-years before their hiatus in 2007, Outkast rose to the top echelons of hip-hop, winning six Grammy Awards, including Album of the Year for their 2003 double album Speakerboxxx/The Love Below.
