The reality-TV star, Rob Kardashian, turned to Twitter out of anger and posted his sister Kylie Jenner's number out for 6.7 million followers to see. After the incident, the celebrity decided to explain on air with Ryan Secreast that he wasn't able to control his emotions because he thought that his fiancée and the future mom of his baby, Blac Chyna, is being excluded from the baby shower by his sisters Kim, Khourtney, Khloe, Kendall, and Kylie.

"I thought they weren't having Chyna at our baby shower. Chyna's baby shower is actually this Sunday, but they were trying to do a little surprise 'guy' baby shower for me, and I was just upset trying to fight for Chyna like, 'Yo, she has to be at the baby shower. She's birthing my child. She needs to be there.'"

He also said that it was only miscommunication on his end.

Rob admitted that he took his anger out on all of his family and it wasn't just Kylie; he was mad and only realized it later that it was totally messed up when he posted Kylie Jenner's number out on public; which he then claimed that it wasn't that serious and that they change their numbers all the time.

According to the 29-year-old celebrity, Kylie, 19, is still totally annoyed with what he did and that she blocked him and didn't give him her new number.

And while Rob was on air, he grabbed the opportunity to apologize to his baby sister as well; saying the words:

"I'm sorry, Kylie, if you're listening. I love you, Kylie."

"We all love each other and we're all family, and I never want to beef or argue with nobody," he added. "I hate when people think, 'Oh they're doing this for ratings. Oh, your show's coming out Sunday.' These are all real issues that are actually happening. It's so many siblings that it's hard to communicate with everybody, honestly."
