Friday night was a family affair for the Kardashian-Jenner clan and the Smiths.
Kim Kardashian, Kourtney Kardashian, Kris Jenner, Kendall Jenner and Kylie Jenner joined Jada Pinkett Smith, Willow Smith, and Jaden Smith for a celebration of Balmain creative director Olivier Rousteing's birthday. Kylie's boyfriend Tyga joined in with the "Balmain Babies" at the fête, as did Kendall's BFF Cara Delevingne.
The celeb-packed guest list also included Jessica Biel and Justin Timberlake; Jennifer Lopez, who cuddled up for a selfie with Kylie, and Casper Smart; Constance Jablonski; Rosie Huntington-Whiteley; Abbey Lee Kershaw; Mary J. Blige; and Jussie Smollett.
Naturally, the gang Instagrammed plenty of selfies and group photos from the night. Everyone seemed to be enjoying themselves at Olivier's B-Day get-together, which game just a few days Kanye West threw a surprise party for Kim's 35th.
Khloe Kardashian was, understandably, absent from both celebrations as she continues to be by Lamar Odom's side and supporting him on his road to recovery. The Keeping Up With the Kardashians star did make sure to wish Kim a happy birthday on Instagram, though, writing, "Happy birthday Keeks!! I pray you know how loved and dope you are!!! You continuously amaze me by how you do it all. Thank you for always being there for everyone! Today is about you!!! Enjoy it Mrs West!!! I love you, My bestie, my sister, my rider!"
As has been evidenced particularly in these last few weeks, family is everything to this bunch. Through good times and bad, they can always count on each other for support.
