Rob Kardashian is not playing around.
The reality star and famous Kardashian sibling took aim at his youngest sister, Kylie Jenner, Monday night when he tweeted her real cell phone number to his 6.65 million followers. Apparently, there's some behind-the-scenes beef about an upcoming baby shower.
"Didn't invite the Mother of my child to a baby shower you all were trying to throw for me ? You all must have lost your damn minds," he wrote after sharing Jenner's digits and clarifying his account had not been hacked.
While we know his relationship with Kylie—who has been dating Blac Chyna's ex Tyga for years—has not been so smooth at times, what could have suddenly sparked such a brawl? A source tells E! News the drama boils down to a baby shower planned for Rob that Chyna was not invited to.
