In several Snapchat videos that Kylie, 18, shared with fans, she and Disick, 32, can be seen with their arms around each others’ shoulders as they mouth the words to Post Malone’s “White Iverson” at the 1 OAK and Up&Down–hosted fete.
The youngest Kardashian-Jenner sibling showed off her long, straight peach-hued locks against a plain white T-shirt, and capped off her look with plenty of necklaces and oversize sunglasses.
Twenty-year-old model Kendall, meanwhile, rocked a patterned lace top and tons of necklaces, with her hair swept up and back away from her face.
Disick donned dark shades, a black baseball cap, and a white T-shirt for the event, bobbing his head along to the performance.
Other A-list stars at the daytime get-down included The Weeknd, Bella Hadid, Miranda Kerr, Ruby Rose and even Snapchat CEO Evan Speigel.
VIP guests partied in the Bumble cabanas while the crowd snacked on tacos by Wine N Dine and sipped on Budweiser, while snagging sunglasses by Smoke x Mirrors.
On Friday, Kylie also spent some time hanging at the Paper magazine party (she was their April cover girl), where she noshed on cupcakes and enjoyed a chill afternoon with a special performance by Jaden Smith and Harry Hudson.
The reality star shared a shot of herself posing in front of a blowup image of the cover with a pal via Instagram.
