Alas, another ode to a woman's derriere. R&B singer, Jonn Hart, teams up with legendary Bay area hip-hop artist, E-40, for the remix to "Who Booty." Jonn Hart's hit single is already a favorite on the airwaves, but with the addition of E-40 we're sure this single will rise to the next level. Be sure to listen to the latest rendition of "Who Booty." Trust us, the catchy hook will have you asking, "Who booty is it?," even you don't want to.
