Of course, the usual crew was there: Kourtney Kardashian, Kim Kardashian, Kanye West, Kylie Jenner, Tyga, Kendall Jenner and Khloe Kardashian. There were also a ton of other famous faces including Ryan Seacrest, Chrissy Teigen and John Legend, Will and Jada Smith, Tommy Hilfiger, Kyle Richards and Kathy and Rick Hilton.
According to Us Weekly, the event began with a cocktail hour, where Kris and her boyfriend Corey Gamble greeted their guests. The main event lasted until about 3:00 am, where guests were dancing to tracks spun by DJ Cassidy and enjoying the '20s ambiance.
The family also made a video montage for Kris (inspired by Kris' "I Love My Friends" video from 1985), which featured an original song the fam wrote with the help of Kanye West, called "You Love Your Friends." Kris' ex, Caitlyn Jenner even appeared in the video - sending some love...from the bathtub!
