Justin Bieber broke out a little Tupac while performing with Rick Ross at Gotha Club in Cannes on Monday night, May 19.

While initially serving as the hype man for the rapper, the Biebs -- dressed in a red-and-blue checkered flannel shirt -- pranced around onstage, arms waving, pumping up the crowd for 'All I Do Is Win' (as if his mere presence didn't excite everyone enough!)

But he soon switched up the pace (and his clothing), going shirtless while rapping Tupac's 'Dear Mama' in the crowd, spittin' those rhymes like he owned the place. Of course, Bieber is no stranger to the game, busting out some pretty impressive freestyle raps back in the day. He's also no stranger to showing off his killer abs, especially while in the South of France, going shirtless in the city of Cannes yesterday -- much to the delight of Beliebers everywhere.
