Bruno Mars, B.o.B and Janelle Monae shared the stage Sunday night (Feb 13) as they all performed at the 2011 Grammy Awards. This particular performance was unique because each of the artists assisted one another in their respective songs.

Janelle sang background during B.o.B and Bruno’s “Nothing On You” before the trio transitioned into Bruno’s solo hit “Grenade.” Then, Janelle Monae took over the stage with a performance of her song “Cold War” with Bruno Mars bangin’ on the drums and B.o.B rockin’ it out on the guitar in the background.

Look below for the performances!
