Kim Kardashian West and rapper hubby Kanye were also in attendance for the festivities, ET can confirm. Kim, who has been keeping a low-profile since her traumatic Paris robbery, did not appear to be seen in any social media postings.

Noticeably missing from the soiree was Kendall's older brother, Rob Kardashian and his fiancee Blac Chyna, who are expecting their daughter any day now.

Kendall started off the evening's festivities at Catch LA, stepping out of a car with pal Hailey Baldwin, wearing a skin-tight, lace-up black bodysuit that showed off her killer legs. She paired the look with strappy heels and an olive green fur stole.
