Khloé Kardashian is being brutally honest about how she really felt when her brother Rob Kardashian got engaged to Blac Chyna. In a sneak peek of Sunday’s episode of “Keeping Up With the Kardashians,” Khloé and her sisters dish on Rob’s proposal, and it doesn’t sound like everyone was on board with it.

“Why would we congratulate him?” says Khloé after Kim Kardashian reads a news story about how the family didn’t react to the proposal on social media. “No one should congratulate them. That’s so desperate and fake of whoever does first, because I know someone’s gonna break.”

Kylie Jenner then tells her sisters that her then-boyfriend, Tyga, tweeted he was happy for Chyna and Rob. “I just feel like the world thinks that we care so much, and they’re making it this huge deal, when in reality, none of us really care,” she says to the camera. “We just want Rob to be able to tell us when he’s gonna do something big like this.”

In another sneak peek released earlier this week, Kim said she couldn't care less about her brother and former friend’s engagement. “I don’t care if he tells me,” she said. Kourtney Kardashian was the only one who stuck up for Rob, saying that she doesn’t think they should cause anymore tension and should just be happy for Rob and his new fiancée.

Since the “Keeping Up With the Kardashians” episode was taped, the family appears to have worked everything out. In May when Kim dished on Rob and Chyna’s engagement, and also baby news, the mom of two said she was “really happy” for them. “It’s so exciting,” she told “Entertainment Tonight” at the time. “You know, it’s a really exciting time for them … It’s been a really fun time.”

Chyna and Rob announced their engagement in April after a few months of dating. A month later, the couple revealed even more exciting news: They’re expecting a baby together. Chyna and Rob are believed to be getting married this summer before they welcome their little bundle of joy.
