Fresh-faced Chicago rapper Vic Mensa has previously worked with Kanye West -- he was featured on "Wolves" and performed the track with West on Saturday Night Live -- but now the tables have turned as Kanye performs a guest verse on Mensa's "U Mad," the full version of which was released yesterday (April 10). Check it out below:

The track was listened to on Soundcloud over a quarter million times just seven hours after it was uploaded. Mensa, who is just 21 years old, has no official releases to his name yet and has yet to set a street date for his debut EP.

Mensa is listed as a co-writer on Kanye's "All Day," another track, along with "Wolves," set to appear on Kanye's upcoming album, So Help Me God, which also has no firm release date in place yet. It's widely speculated that Kanye is planning some sort of surprise release.

Kanye's been busy as of late: He admitted he's been a bit of a "douchebag," was called "the only rock star left" by Marcus Mumford and was appointed a god in the fan-created edit of the Bible, The Book of Yeezus.
