Roots of Roll Deep

"Nothin' on You" is a song by American rapper B.o.B, featuring American singer-songwriter Bruno Mars. It was released by Rebel Rock, Grand Hustle, and Atlantic Records on December 15, 2009, as the lead single from B.o.B's debut studio album, B.o.B Presents: The Adventures of Bobby Ray (2010). The track was written by B.o.B, Mars, Philip Lawrence, and Ari Levine, with the latter three producing it as the Smeezingtons. "Nothin' on You" was initially written for Lupe Fiasco, but Atlantic Records's chairman, Craig Kallman, gave it to B.o.B after being displeased with Fiasco's version. The song took several months to finish and was born from a hummed melody by Mars and Lawrence.
