Justin Bieber just can't help himself!
The troublemaking singer ripped off his button-down to heat up a night of partying at the Cannes Film Festival 2014's Gotha Club with Rick Ross.
JB probably doesn't have a movie to promote, but how could our bad boy miss an A-list party!
At this point, we barely recognize him with his shirt on! LOLz!
