Earlier this month (January 9), the duo revealed that they would be making their live comeback headlining Coachella Festival in California alongside Muse and Arcade Fire in April.
They subsequently announced another headline slot at New York's Governors Ball festival, which takes place June 6-8 on Randall's Island.
According to Pitchfork, the reformed duo have now announced a 40-date full world festival tour "to celebrate the 20th anniversary of their unique and influential sound." While the exact dates are yet to be announced, the first gig on the mammoth stretch will be at Coachella.
"It's truly an honour to celebrate 20 years and still be free to do music the way we choose," Big Boi said in a statement. "Don't just think outside the box, know that there is no box. I'm looking forward to rocking the stage with my Bro Ski and to all the fans - stank you smelly much, this is for y'all!"
Andre 3000 added: "And imagine, all we wanted to do was rap! I am thankful to have been a part of a group that allowed me to explore anything that came to mind and have fun doing it. Returning to the stage together is the most exciting way for us to thank everyone for their 20 years of supporting OutKast."
OutKast went on hiatus in 2007 and have not performed together since 2004, each enjoying solo success in the subsequent years. This year is the 20th anniversary of the pair's 1994 debut album "Southernplayalisticadillacmuzik."
In the other news, the band is reportedly making new music, according to Consequence of Sound.
During an appearance on the Howard Stern Show this morning, the duo's ex-manager Queen Latifah spoke briefly about her time as head of management company Flavor Unit. Seemingly unaware of the duo's reunion, Stern asked Latifah what happened to OutKast, to which she responded, "They're chilling ... They're doing movies ... They're about to work on a new album."
Latifah was quick to add, however, that she no longer manages OutKast. She also made no mention of their upcoming tour, and before she could divulge any other info, Stern moved on to a different topic.
