Talk about sexual tension! Kourtney Kardashian isn't afraid to party with her exes and look HOT while doing it!

The mother-of-three hit up The Nice Guy, on Friday, with sisters Kylie and Kendall Jenner AND with ex-boyfriends Younes Bendjima and Luka Sabbat also cozying up to the clan in a VIP booth! Awkward? Nah! This lady's used to run-ins like this, as the insular family keeps their friends close and their exes closer!

Kourt sported a tight dark-brown tank with matching leather pants and strappy heels -- one of her favorite go-to looks.

The group was there to celebrate the birthday of Kendall's podcast partner Daniel Chetrit. Speaking of Kendall ... HER ex, baller Ben Simmons was there, too!

Kylie seemed to be the only one without a former love interest in attendance (but who knows, right?!), as she kept it on the DL for a rare night out with pal Stassie Karanikolaou, wearing a dark brown D&G mini-dress (is this the new on-trend color?) with chunky white sneakers, Stassie looking like her fashion twin in a black hoodie, black biker shorts, and matching chunky white sneakers.

But why hid, Ky?! We need to see your pretty face!
