Olivier Rousteing celebrated his 30th birthday last night, and not just anyone was invited; the Balmain creative director's guest list was studded with Hollywood’s most elite, from Cara Delevigne to Tyga, who performed at the party. 

Long-time friend Kim Kardashian pulled up with her famous fam, and some members of the Smith clan—Jaden, Willow and Jada—were also in attendance. Both families took full advantage of the group selfie opportunity, which you can see below. What a time to be on Instagram.
