The rumoured couple let their hair down at West Hollywood club Penthouse following a special guest appearance from French, who sported his favourite set of gold chains as they made their way onto the street in the early hours.
Accompanied by a troupe of bodyguards, Kourtney, 29, led the way in a smart black ensemble comprised of tight fitting top and jeans.
As always, a camera crew appeared to accompany Khloe as she and French climbed into her white Range Rover and sped off into the night.
The couple had good company at the club in the form of Khloe’s older sister Kim Kardashian – who left separately.
French confirmed her presence with an shot posted on his Instagram shot earlier that night in which she throws the camera a peace sign while standing next the rapper.
