Three of music's most exciting newcomers, B.o.B, Bruno Mars and Janelle Monae, teamed up for a medley of some of their biggest hits tonight at the 2011 Grammy Awards.

All three artists changed up the arrangements on their familiar songs. Sporting a tuxedo and monocle, rapper B.o.B opened the medley with a relaxed version of his No. 1 hit 'Nothin' on You,' backed up by an orchestra. The screen then turned to black and white as Mars performed an old-school doo-wop version of his latest chart-topper, 'Grenade.'

Showing off her unique style with a men's suit and her trademark pompadour, Monae followed with an energetic performance of 'Cold War,' complete with a stage dive into the crowd, that may have the Academy wondering why it only awarded her two nominations.

Mars already won the Grammy tonight for Best Male Pop Vocal Performance, while B.o.B. and Monae are both multiple nominees.
