Khloé Kardashian felt "internally sad" when she learned her brother Rob Kardashian is expecting a baby with Blac Chyna. The former 'Kocktails with Khloe' host - who kicked the sock designer out of her home when she discovered he was dating the make-up artist earlier this year - and her sisters Kim Kardashian West and Kourtney Kardashian held clear-the-air talks with their younger sibling, who wanted to apologise after they found out about his engagement online, but she didn't seem to take the rest of his happy news too well. While Kim and Kourtney - who has kids Mason, six, Penelope, three, and Reign, 18 months, with ex-partner Scott Disick - congratulated their brother, Khloe held her head in her hands. In scenes which aired on 'Keeping Up With the Kardashians' on Sunday (03.07.16), she muttered: "Congratulations. I don't know my emotions right now, I know I feel, I feel more empty and more unresolved than anything else and I'm like internally sad." Despite her reaction, the 32-year-old star later insisted a baby would be a "blessing" and she hoped it would help Rob continue to rebuild his life following his battle with depression and struggles with his weight. She said: "I do think a baby is a blessing, I think that if this is gonna get Rob to get his s**t together cool. "But I personally don't know what the next step for Rob and his girlfriend and all of us are. That's up to Rob." During their conversation, Rob insisted the only reason he hadn't told his family about his plans to propose was that it happened "spontaneously". However, Kim - who has children North, three, and Saint, six months, with husband Kanye West - said: "Do you understand that that was hurtful to us that we found out about your engagement on social media? I think we just want that acknowledgement." Her apologetic sibling replied: "Yes I understand but I wasn't even thinking that at the time it happened so fast. "I get I upset you guys, I get I'm your brother, only brother, you would like to know when something important like this happens. I apologise because I wasn't trying to be rude."
