Justin Bieber Is Partying His Butt Off At Cannes! See Who He Rubbed Elbows With HERE!

Is Cannes big enough for him?
Sure looks that way!
Justin Bieber made the rounds at the film festival in France, and he ran into more than a few stars!
Including Entourage‘s Adrian Grenier at the Vanity Fair and Armani party!
But he didn’t stop there!
The star also got down with Paris Hilton at the GOTHA night club later on in the evening!
After a long evening of fun and dancing the star looked exhausted as he made his way through a crowd of his adoring French fans before finally calling it a night!
We’re glad the star is finding out he can have fun without drugs! Hopefully he can continue to function without any of that!
