See all the stylish snaps from the night, here...
amfAR, as ever, saw a stellar turn out at the annual Cannes Gala last night.
Karlie Kloss led the glamour wearing a floor-grazing black gown. She complemented her fabulous feather trimmed floor-sweeper, complete with split-front detail, with a slick of red lipstick.
Heidi Klum was another catwalk icon to champion the split-front gown, alongside fellow supermodel Alessandra Ambrosio, who chose to add an extra edge of glamour to her look with some dazzling diamonds and a super-smoky eye.
LBD's were a popular choice at the glitzy event, with the likes of Lara Stone and Bella Hadid donning chic black creations, proving that classics can indeed be cool when it comes to red carpet dressing.
Elle Fanning used the amfAR bash as a chance to showcase her fashion credentials wearing a beautiful printed gown that fitted in all the right places, with an extra swishy skirt for maximum impact.
One VIP keen to do something a little different was Katy Perry. For her turn on the red carpet, Katy slipped into a red full sleeve, full skirt number, and finished the showstopping look with a slick low updo, a sweep of matchy-matchy red lipstick and of course, a red manicure. It's all in the detail, after all.
Also bringing the glamour was Rosie Huntington-Whiteley, who never fails to impress in the style stakes. And this latest Cannes look was no different. The beautiful Brit model wowed in a metallic bandeau gown and wore her long blonde hair in a sleek centre parting, finishing the look with some incredible drop diamond earrings.
