amfAR Gala has been established to raise funds for the fight against AIDS and this was Aishwarya 's fourth year at the charity gala.
Other L'Oréal Paris ambassadors who attended the event were Eva Longoria, Doutzen Kroes, Barbara Palvin, Natasha Poly, Karlie Kloss and Lara Stone.
Longoria looked pretty in a powder grey gown with a plunging neck and she completed her look with smokey eyes, dewy make-up and hair tied in a loose chignon. With nude makeup being the rage on catwalks this season, Kroes, Palvin, Kloss and Poly opted for it.
While Kroes and Palvin looked hot in red high-neck ensembles, Kloss rocked the vintage look in an ivory sequin embellished high neck gown, said a statement.
Poly and Isabelli Fontana looked ravishing in gorgeous black gowns.
