Di'Jonn Grizzell, professionally known as Jonn Hart, is an R&B singer from Oakland, California. He first experienced mainstream success in 2012 with his song Who Booty, which gained major traction first in California, before garnering nationwide acclaim. Who Booty eventually reached #1 on the US Billboard Rhythmic Charts, and the excellent performance of this song was in part helped and validated by the multiple remixes of the song that were released shortly after the song came out. Different remix versions of Who Booty include one with East Coast rapper French Montana, and another with fellow Bay Area rappers E-40 and Clyde Carson, the former of which received major play radio following the song’s release.
