Plus, Kendall says Kylie's priorities aren't straight, and Scott Disick in tears.
From the look of things, this might be the most intense season of Keeping Up With the Kardashians yet.
The series' season 11 super tease shows the roller coaster year the reality family has had, starting with Kourtney Kardashian's absolutely stunning NSFW photoshoot amid her split from Scott Disick.
"I just don't think Kourtney realizes how bomb she is right now," notes Kendall Jenner of her sister, as Kourtney gets shy during a photoshoot and says, "Let's not shoot my vagina."
Meanwhile, Scott, who went to rehab after he and Kourtney broke up, is in tears during the promos, showing clear remorse for his infidelity over the summer.
"I made the worst decision I could have ever made in my life," says a teary-eyed Scott, after being confronted by the family. "This is a situation I never thought I'd be in."
More big reveals from the super tease include newly 18-year-old Kylie's relationship with Tyga, 25, as Kendall worries that her life is not in order.
