Balmain designer Olivier Rousteing marked his 30th birthday with an over-the-top bash in LA on Friday, and, of course, Kim and Kourtney Kardashian were on hand to celebrate. The ladies, who are close friends with Olivier, were accompanied by their sisters Kendall and Kylie Jenner as well as their mum, Kris Jenner, and her boyfriend, Corey Gamble. Also in attendance was Kylie's other half, Tyga, who performed at the event, and Kate Hudson, who made a jaw-dropping appearance in one of Balmain's designs.
Although Khloé Kardashian did not attend, the Kardashian-Jenner clan made the most of their night, socialising with the likes of Mary J. Blige, Cara Delevingne, and family friends Jaden, Willow, and Jada Pinkett Smith. Kim and Kourtney took to Instagram to share even more snaps from the extravaganza, including a handful of selfies featuring the Smith family.
