After promising to headline over 40 music festivals this year, OutKast is keeping their word. Last night, the duo took over Adult Swim's Upfront party in New York City with a special show.

Celebrities like Nick Cannon, Mike Tyson and Questlove were all reportedly at the Terminal 5 venue, enjoying a set that included cuts like 'B.O.B.' and 'So Fresh, So Clean.' "At the sound booth in the cut at this secret Outkast show. Shhhh.. I snuck out the house LOL," shared Nick on Instagram.

Adult Swim has a history of big names perform at its annual Upfront party. Last year, Kanye West took the stage and surprised the crowd with a new song and rant.
