Celebrities flocked to Cannes Film Festival on Thursday, May 21 to attend amfAR's Cinema Against AIDS Gala. Runway beauties Kendall Jenner and Gigi Hadid were among the familiar faces coming to the event taking place at Hotel du Cap-Eden-Roc in Cap d'Antibes, France.

Fresh off the "Youth" premiere the previous day where she wore a Azzedine Alaia black dress which consisted of a cropped top and a full skirt, Jenner opted for a similar midriff-baring look with a long flowing skirt for amfAR. This time, she opted for a maroon number by Calvin Klein.

Hadid was stunning in a Tom Ford white dress with a sexy thigh high slit and a gaping hole that left little to imagination in the cleavage department. The ex-girlfriend of Cody Simpson teamed the long-sleeved, high-necked gown with a pair of Aquazzura nude booties.

Sienna Miller glittered the red carpet in a Ralph Lauren metallic dress with spaghetti straps. Marion Cotillard added vibrant color with her strapless green column dress by Jean Paul Gaultier. Michelle Rodriguez and Rita Ora were red hot in Zuhair Murad and Marchesa respectively.

Eva Longoria flunted her cleavage in a baby-blue dress from Georges Hobeik collection while Diane Kruger looked chic in a Chanel number that showed off her tone legs with its mini feather skirt. Mary J. Blige opted for a strapless Versace white dress sparkling with Swarovski crystal beads.

Antonio Banderas, Jake Gyllenhaal, Irina Shayk, Paris Hilton, Chanel Iman, Adriana Lima, Dita Von Teese, Charli XCX, Adrien Brody, and Karlie Kloss were also in attendance.
