The other high profile guests at the star-studded event included supermodels Irina Shayk, Toni Garrn, Doutzen Kroes and Laura Stone, Desperate Housewives star Eva Longoria, Spanish actor Antonio Banderas, British actress Sienna Miller and French star Marion Cotillard among others.
Fetching in a mauve Elie Saab gown, Ash completed her look with diamond jewellery and her hair styled in soft waves.
Conspicuous by his absence was her husband, actor Abhishek Bachchan, who usually escorts her to the event each year. He had tweeted earlier
Unfortunately due to work commitments I can't attend the AMFAR gala today. But the better half is there to represent.— Abhishek Bachchan (@juniorbachchan) May 21, 2015
The actress who is a big draw at the festival, picked a white Ralph & Russo dress for her previous red carpet look on Wednesday. Her first, on May 17, was in a teal gown, again by Elie Saab and turned the fashion police upon her. She redeemed herself somewhat with a claret Oscar de la Renta gown at the launch of her comeback film Jazbaa on May 19.
