Justin Bieber amfAR Party

Be still our hearts!

Justin Bieber attended last night's amfAR gala at Cannes, and the singer ditched his trademark shirtless with gold chains look in favor of a sophisticated suit!

The Biebs has been flirting up a storm with all types of beautiful ladies since he arrived at the film fest, and if you believe the rumors, it's because he's on a quest to see how many hotties he can bed!

The Canadian sensation apparently told a pal he "wants to bang as many models as possible", according to Hollywood Life.

Somewhere Selena Gomez is crying!
