With 14 nominations between them, B.o.B, Bruno Mars, and Janelle Monáe tag-teamed during their empowering Grammy Awards performance, with each artist backing up one another as they sang their hits.

A monocle-clad B.o.B. kicked off the triple threat with an acoustic rendition of “Nothin’ on You,” getting a hand from Bruno on piano and Janelle playing the synth. Bruno soon took over with a ’50s-inspired rework for “Grenade,” framed in black-and-white with B.o.B holding it down on the keys.

Janelle Monáe capped of the performance with a fiery version of “Cold War” where B.o.B took on guitar duties and Mars rocked it on the drums. The bouffant-sporting chanteuse stage-dove and sang her heart out, earning a standing ovation from her peers.
