Kris Jenner called daughter Kourtney Kardashian's ex-boyfriend Scott Disick "a piece of s---" on the season finale of "Keeping Up With the Kardashians," which aired on Sunday, Oct. 11.

The ex-wife of Caitlyn Jenner is definitely not holding back when it comes to how she feels about her eldest daughter as seen in the brief video, Us Weekly reported.

Kardashian cousin Cici Bussey called Kourtney's sister Kim Kardashian and revealed to her that there were photographs of Scott surfacing like wildfire on the Internet lying down with his arms around another girl, International Design Times informed.

"No! That piece of s---!" Kris said upon hearing it and looks online for the snaps. "It's just embarrassing," the pregnant wife of Kanye West added.

"It's disrespectful. I think I've often made excuses for Scott, and it's just getting tougher and tougher," the 59-year-old momager told Kim after cooling down. "I think it's about time," the 34-year-old social media maven said.

Kourtney and Scott separated in early July after he was spotted getting cozy with ex-girlfriend Chloe Bartoli in Monaco in South of France. The ex-twosome share three children together -- Mason, 5, Penelope, 3, and Reign, 9 months.

Meanwhile, Kourtney is making a time on her own while her ex-boyfriend is spending most of his time dating several girls. As a matter of fact, she was spotted with Justin Bieber on at a West Hollywood club on Friday, Oct. 9.

The two went to club together and hit the Universal Studios right after. The 21-year-old Canadian crooner and 26-year-old reality star also ate dinner and were even seen leaving together in the same car.

Kourtney sported a very casual look in a tan top paired with white pants while Justin donned a camouflage jacket and a gray hat. It's kind of not surprising to see the "What Do You Mean?" singer hanging out with a member of the infamous family since he is known to be close to them.

As a matter of fact, Justin recently shared a snap with Kendall Jenner. In May, he also posted a photo of Mason and him playing in the pool. "Mason is cool as a fan," the ex-boyfriend of Selena Gomez captioned the sweet photo of Mason riding on his back.
