Summer Jam XX promised a slew of surprise guests, and Hot 97's annual concert delivered. Nicki Minaj came out with 2 Chainz. Lil Kim joined Fabolous during his set. Ol' Dirty Bastard's son spit his late dad's verses during Wu-Tang Clan's time on stage. J. Cole snuck out for "Power Trip" during Miguel's set, but it was Miguel's other guest, Mariah Carey, that was the big surprise.
Wearing her white summertime shorts, Mrs. Cannon joined Miguel for their collaboration "#Beautiful." The concert, held at MetLife Stadium in East Rutherford, NJ, was streamed live for those who couldn't make it out. Watch footage of Mariah performing with Miguel below.
