Kylie’s boyfriend Tyga was also in attendance, along with her ex-boyfriend Jaden Smith and his own family. Jada Pinkett-Smith and Willow Smith made it a family affair for the Smiths as well as the Kardashian-Jenners.

According to Entertainment Tonight, other A-list stars were in attendance. Jennifer Lopez and her boyfriend Casper Smart were at the party, along with Balmain Army models Cara Delevingne and Rosie Huntington Whiteley.
