When Lil B isn't harassing some of the NBA's finest, he's apparently making music with one of hip-hop's finest: Chance the Rapper.

Chance on Saturday shared a photo of himself with Lil B (seen above), noting that the two "made an album" together. Lil B subsequently posted the same picture on Tumblr, claiming they've created "a based freestyle album."

The two MCs are currently in Chicago, where Chance is scheduled to headline Pitchfork Music Festival on Sunday night.
