Scott and Kourtney arrived separately to the party. They were spotted hugging and acted very cordial towards one another, a source told E! News, adding that Scott spent most of his time with Khloe and Kris Jenner. His and Kourtney's children did not attend the bash.
Scott also hung out with friend and nightclub entrepreneur David Grutman and his wife. A source told E! News exclusively that the reality star was "on his best behavior" and was not seen drinking.
"Oh, you guys, look at the whole gang, the whole family is here," Kim said in another video showing Scott, Khloe, Caitlyn Jenner and Kanye West.
Celebrity guests included Ashley Benson, Chris Brown, Cara Delevingne, Kevin Durant, Bella Hadid, The Weeknd, Winnie Harlow, Khloe's ex French Montana and Dave Chappelle, who joined Kylie's boyfriend Travis Scott on the mic.
