How did Kim Kardashian feel about Kylie Jenner and Tyga's relationship?
She's revealing that answer on Sunday's Keeping Up With the Kardashians!
In this clip above from the episode, Kim is spending time with Khloe Kardashian and Kourtney Kardashian when she tells them a story about how she recently hung up on Rob Kardashian's fiancée Blac Chyna.
"So I called Rob and he said that Chyna wants to talk to me and you know I just told him that I'll talk to her when I'm ready," Kim explains. "And so he put me on speaker and then he was like, 'Oh Kim, Chyna's in the room, I just wanted to tell you so you didn't think I was alone.'"
Kim then heard Blac Chyna say "hi" in the background but Kim "didn't say anything" because she "froze."
Rob then told Kim he was going to go brush his teeth and passed the phone to Blac Chyna.
"And so I go, 'OK gotta go bye.' And I hung up," Kim explains.
She then goes on to talk about how Kylie's relationship with Blac Chyna's ex Tyga "completely broke Chyna's heart."
Kim explained that it "absolutely" was "uncomfortable" for her when Kylie and Tyga started dating, mostly because Blac Chyna was Kim's friend at the time. But she had "no choice" but to take Kylie's side.
