Justin Bieber seems to be going through a lot of antics to build up his street cred lately. If getting arrested and hanging with Birdman and Wayne weren't enough, he is now trying his hand at rap. 

The 20-year-old singer was recently caught showing off his rhyming skills while in Cannes at the annual film festival. During a club performance by Rick Ross, the young pop star jumped on stage to perform Tupac’s "Dear Mama."

After the impromptu performance,  Bieber took to Twitter to tweet a picture of himself and Ross with the caption that read “Boss.”
