VIDEO : Guess What Kourtney Kardashian Wore to Scott Disick's Birthday Party!

Kourtney Kardashian and Scott Disick jetted off to Las Vegas over the weekend to celebrate her 36th birthday at a party at the 1OAK nightclub in the Mirage Hotel & Casino.
Kourt, who gave birth just four months ago to her and her longtime beau's third child, son Reign, showed off a trim figure in a chic, black, long sleeve mini dress with an empire waist and a flared skirt, paired with matching gladiator heels. Inside the club, she and Disick, 31, got cozy.
The two were presented with giant cardboard pictures of their faces.
The exact same props were also seen at mom Kris Jenner's 59th birthday party at the same club last November.
