Nothin' on You

"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.

"Nothin' on You" is a pop rap, R&B and Southern hip hop ballad. Some music critics praised its sweetness and positive vibe, while a few criticized Mars's performance. Lyrically, the song aims at a woman's heart with flattery. The song peaked several worldwide music charts, including its native United States and the United Kingdom, and peaked at number the three and five in Australia and New Zealand, respectively, and the top ten in Canada. It was certified six times platinum by the Recording Industry Association of America (RIAA), triple platinum by Recorded Music NZ (RMNZ), and once by Australian Recording Industry Association (ARIA) and Music Canada (MC).

The music video, directed by Ethan Lader, was filmed in Los Angeles. It features cutout animation, which takes multiple collages and taps them one over each other, in this case depicting various women. The video is interpolated with footage of the performers playing instruments along with Lawrence. The track has been covered by various recording artists and parodied by "Weird Al" Yankovic. It was nominated for Record of the Year, Best Rap Song and Best Rap/Sung Collaboration at the 53rd Grammy Awards. The song was performed live at The Ellen DeGeneres Show and at the 2010 MTV Video Music Awards. Both artists have promoted it during several of their respective tours.
