Kourtney Kardashian went out to celebrate her on-again, off-again hookup's birthday, and even without getting all glammed up she still looked amazing.
The 39-year-old Kardashian sister showed up Monday night to the Peppermint Club in West Hollywood for model Luka Sabbat's 21st birthday party.
Wearing a long leather jacket and corduroy pants, Kourtney was way more covered up than usual, but it was also pretty chilly in L.A.
It's unclear what Kardashian got Sabbat for his birthday, but the two stars did end up leaving the club together early Tuesday morning. Maybe he got a sneak peek of her stripped down photo shoot with GQ Mexico.
