Scott Disick spent much of Friday night with ex-girlfriend Kourtney Kardashian's sister Kylie Jenner and the teenager's beau Tyga.
The three were photographed near the West Hollywood nightclub 1 OAK, which hosted The Weeknd's Beauty Behind The Madness official album release party, around 2 a.m.
Kylie, 18, sported a short blue and black wig, sunglasses, a black Moschino crop top, a mid-length white double-breasted jacket and black suege thigh-high boots. Scott, 32, wore a tan jacket over an olive T-shirt, Tyga, 25, sported a blue baseball cap, chains and a black printed T-shirt.
Kylie posted a selfie video showing her and a friend on Instagram hours earlier.
Scott has been mostly keeping up with his club appearances since Kourtney Kardashian, 36, broke up with him over the Fourth of July holiday. It is unclear if Scott, who has battled substance abuse and has undergone stints in rehab, most recently just after the split, was drinking alcohol on Friday night.
On Friday night, Kourtney posted photos of herself enjoying some mommy-son time with her and Scott's youngest child, son Reign Disick, who is 8 month old. She and Scott are also parents to son Mason Disick, 5, and daughter Penelope Disick, 3. Scott has spent time with their kids since the split.
He and Tyga, a longtime Kardashian and Jenner family friend, hung out earlier this week. The two were photographed together near Barneys New York in Beverly Hills.
