In addition to revealing Kourtney was a big drinker back in the day, Kim also said there was about a "2 percent" chance her mom, Kris Jenner, would ever speak to Caitlyn again.
She said the only reason they would ever potentially talk would be because of Kendall and Kylie.
The 36-year-old mom of two, who just celebrated her third anniversary with Kanye West, also discussed her previous marriage to Kris Humphries. She said she knew it wasn't going to last on the honeymoon.
Speaking on her decision to marry Humphries in the first place, she told Cohen,
I just thought, 'Holy sh*t I'm 30 years old, I better get this together. I better get married.' I think a lot of girls do go through that where they freak out thinking they're getting old and they have to figure it out, and all their friends are having kids. It was more of that situation.
Kim and Kris are old news, though. A much hotter topic is the recent breakup of Kylie Jenner and Tyga.
Kylie and Tyga have been on-again-off-again since 2015 but called it quits (again) a couple months ago. From the sounds of it, this time it might be permanent.
Playing a game of "Plead The Fifth," Kim was asked what she thought of her younger sister's breakup from the rapper.
You know, I was... it doesn't mean he's a bad person, at all -- I just think that sometimes people… and what was great was that it was so easy, that split. There has not been any drama with her.
A drama-free breakup sounds nice, although a little difficult to believe. Tyga had become a regular in the Kardashians' lives, accompanying them at most major family gatherings.
Kylie appeared to have become quite close with his son, King Cairo, too.
In April, a source said,
They tend to take little breaks all the time and then get back together. It's definitely possible they'll work things out again.
It's looking pretty permanent right now, but I guess only time will tell.
It definitely sounds like Kim is ready for this chapter in her sister's life to be over. While she didn't say anything negative, she did appear pleased with the end of their relationship.
