Heidi Klum - amfAR Cannes Gala 2012

Heidi Klum rocks a sheer Marchesa gown at the 2012 amfAR Cinema Against AIDS Gala on Thursday (May 24) at Hotel du Cap-Eden-Roc in Antibes, France.

The 38-year-old model and Project Runway host finished off her look with Lorraine Schwartz jewelry and Christian Louboutin heels.

Before attending the benefit, Heidi wore another Marchesa dress while attending The Paperboy‘s red carpet premiere during the 2012 Cannes Film Festival.

“What a gr8 way 2 get around ‪#Cannes2012‬! My hair stylist Michel Aleman might not like all this wind in my hair though!” Heidi tweeted with a pic of her lounging on a yacht.
