Justin Bieber is getting down with Hustle Gang. During his productive trip to Atlanta, the pop superstar logged some studio time with the King of the South himself, T.I.

“In the studio with TI,” tweeted Bieber, who also changed his Instagram name to “Bizzle.”

T.I.’s sons, Messiah and Domani, also got to meet the Biebs. “@bizzle came to parlay w/Me & da #familyhustlegang we puttin in #WORK #hustlegangovererrrthang,” said Tip.

Justin has been racking up his hip-hop collaborations while in ATL. He was recently in the lab with T-Pain and hit the club (and studio) with Diddy, Rick Ross, Wale, and Jermaine Dupri.

“Say what you want about @justinbieber but that man is about to drop some of the best music I’ve heard in years. YEARS!!” declared T-Pain.
