B.o.B proves that he can perform with Taylor Swift, but still be ratchet on his twerking anthem “HeadBand” featuring 2 Chainz.

“Drop that ass down,” commands the Atlanta rapper over the whistling DJ Mustard-produced beat.

The single hits iTunes on May 21, while B.o.B’s third album Underground Luxury is due later this summer.

“This project is a lot more effortless than anything because I’ve really shown the full spectrum of what I can do musically, so now I’m just having fun with it. I’m 24 years old, so I’m partying,” B.o.B told Rap-Up TV.
