Scott Disick Hangs Out With Kylie Jenner and Tyga at West Hollywood Nightclub

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.
