The dad-to-be admitted that his social media revenge was misplaced. "I kind of took all my anger out on Kylie and my family. It wasn't just Kylie, it was my whole family. I went in on them on group text. And I was just being petty and posted [Kylie's] number. I was like, 'Yo, it's not that serious. We change our numbers all the time."
Kylie did change her cell phone number and hasn't given her new digits to her big brother just yet, but that doesn't necessarily mean there's more drama ahead.
"We all love each other and we're all family and I never want to beef or argue with anybody," he said. With a family as large as the Kardashian/Jenner clan, there's bound to be some miscommunication—but Rob says it's never just for the cameras. These are "all real issues that are actually happening. It's so many siblings that it's hard to communicate with everybody, honestly."
It's so hard that Rob took advantage of the airwaves to send his sister a message. "I'm sorry, Kylie, if you're listening," he said. "I love you, Kylie."
One thing he and his fiancée don't love are the ongoing reports that they're on the border of breaking up. After all, they answered Seacrest's call from bed—together. "We've been together the whole time, so I can't stand when people run stories like that," he said. "Honestly, I didn't even know we were split up...I thought they were talking about me going in on my sister on Twitter or something like that.
According to Kardashian, their relationship has been a "bumpy road, but a great road."
"We've had our days, but there's never been a doubt in my mind. I always wanted to be with Chyna, always want to be with the woman I'm about to have a baby with," he explained, referencing his famous father Robert Kardashian, who had four children with Kris Jenner before their divorce.
