WATCH: Scott Disick Disses Ex Kourtney Kardashian About Hooking Up With Justin Bieber!

Is Scott Disick getting the last laugh?

In a sneak peek clip for Keeping Up With The Kardashians, Scott, his ex Kourtney Kardashian, Khloe Kardashian, Kylie Jenner, Tyga, and some pals play the game Cards Against Humanity during their family ski trip.

Kourt draws a black card that says, "Why am I sticky?" The 37-year-old begins to read out the white cards that were played saying, "a fleshlight, your weird brother, still being a virgin," and finally, "Justin Bieber."

As soon as the young pop star's name is said, Khloe bursts into laughter. It even got more obvious and awkward that it was a total diss about her alleged fling with the 22-year-old singer once Scott chimed in. "I put that one," Scott tells Khloe with his cards covering his mouth.
