The star-studded birthday bash of Balmain Olivier hosted the leading fashion divas of Hollywood like Kendall Jenner, Rosie Huntington-Whiteley, Jennifer Lopez, Kylie Jenner, Kim Kardashian, Cara Delevingne etc. The girls looked extremely gorgeous & I personally loved Kendall Jenner's outfit. Her hair & makeup too were done to perfection! What do you think?
