Soulja Boy had “The Tonight Show” going “Hammer” with some help from a full band. Dressed in his collegiate swag, S. Beezy turned the volume all the way up with the Boi-1da-produced single from his third album The DeAndre Way, crashing into stores November 30.

Bruno Mars exploded on Thursday’s “Late Show with David Letterman” with his latest single “Grenade.” The Hawaiian heartthrob played his brand new guitar, named “Sweet Terilisha” after a fan on Twitter. Bruno will perform on “The GRAMMY Nominations Concert Live!!” airing December 1 and we’re sure he’ll be picking up some nominations.
