It's safe to say Khloé Kardashian wasn't exactly thrilled about her brother's engagement to Blac Chyna.
Previously on Keeping Up With the Kardashians, Khloé told her sisters that it would be "desperate and fake" if any of them congratulated Rob Kardashian on his surprise engagement -- especially considering the family's complicated history with Chyna.
In this clip from Sunday's episode, the 32-year-old reality star says it's "crazy" that Kris and Kylie Jenner made peace with the soon-to-be Angela Kardashian:
Kris, who previously said she was "in shock" over Rob's engagement, has since decided she needs to "let go a little bit," while Kylie sat down with her big brother and Chyna and posted on Snapchat that they've been "best friends" the whole time.
"It makes me so happy that Kylie was able to be so mature and sit down with her brother and Chyna and really get some of the past issues talked about," Kris explains on KUWTK. "The next step, I think, is really for my other kids to follow in Kylie's footsteps.
A source told ET that Kylie was "over" the relationship. "It was tough for her in the beginning. But she sees how happy he is and all she wants is for him to be happy," the source said.
Khloé has since come to terms with Chyna too, as the two snapped selfies together at Khloé's birthday party this week.
As for her own love life, Khloé recently slammed tabloids for writing sexist dating stories about her, claiming, "Men don't get that reputation!" Find out more in the video below.
