On Sunday night's episode of "Keeping Up with the Kardashians," Rob Kardashian not only told sisters Kim, Kourtney and Khloe about his engagement to Blac Chyna ... but dropped the baby bombshell on them as well.
Suffice to say, it didn't go over well.
"There's one more thing I want to talk to you guys about," he says after talking to them about the proposal. "I don't want you guys to get mad."
It's Kourtney who guesses his announcement: "You're having a baby?"
"I'm being Bible, I'm being dead ass [serious], Rob explains after Kim questions him.
"I've been trying to do this, I'm not even kidding. This was really my decision, it really wasn't hers, on dad's grave," he adds.
"I want you all to be a part of it. There needs to be a talk between you guys," Rob continues. "She's going to be in your lives forever."
Kourtney offers up a genuine "Congratulations," with Kim following suit. Khloe, however, won't even look at her brother as all this is happening -- as she keeps her head down in her hands in shock.
She says, "Congrats," under her breath ... and no, it doesn't sound all that sincere.
"I'm, like, internally sad," she later says in a confessional.
While they all clearly went through a bit of shock after learning the news, it seems like the family has since mended fences. Rob and Blac Chyna were both on hand at Khloe's birthday bash last week.
