Actors, models, and musicians mixed and mingled at the amfAR Cinema Against AIDS Gala  during the Cannes Film Festival in France on Thursday. The annual charity fundraising event brought out stars like Jessica Chastain, Adrien Brody , and Marion Cotillard, who walked the red carpet with iconic French actress Catherine Deneuve. Also on hand for the high-profile party were veteran amfAR supporters Sharon Stone , Jane Fonda, and Kylie Minogue , as well as stunning catwalkers Rosie Huntington-Whiteley, Alessandra Ambrosio, and Victoria's Secret model Barbara Palvin, who recently made headlines when she stepped out with fellow gala attendee Justin Bieber  earlier this week. Justin and Barbara were previously linked back in 2012 and reignited the romance rumors when they met up at Roberto Cavalli's yacht party on Wednesday night .
Justin seems to be having lots of fun at the festival this week — so far he's been spotted hanging with Robert Pattinson at a Vanity Fair bash  and hitting the club shirtless with Leonardo DiCaprio  — but he's not alone; lots of other celebrities have flocked to France for all the fun , and we've been keeping up with all the Cannes glamour  as it happens.
