Rapper Andre 3000 joined Big Boi at College Park's Woodward Academy Saturday, where Big Boi's youngest son Cross "The Boss" Patton was graduating from high school. He'll be attending the University of Oregon this fall and taking his new graduation present (a blue Tesla!) with him.

"It's been 1 hell of a journey, raising 3 Kids, private school to College Degrees,” Big Boi wrote on Instagram.

OutKast’s last production together debuted back in 2006 before both Big Boi and Andre 3000 sought solo work. In 2014, the pair reunited for a massive tour that included headlining at Coachella.
