Rob Kardashian is feuding with his famous family again — and this time, Kylie Jenner's the target.
After his little sister reportedly didn't invite Blac Chyna to a baby shower, Rob, 29, retaliated by releasing her cell phone number to his 6.66 million followers on Twitter.
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 ,,,🙋🏿— ROBERT KARDASHIAN (@robkardashian) September 27, 2016
The sock designer, who revealed in 2013 that Kylie, 19, was his favorite sister, also made it clear that posting her digits was intentional.
"I ain't hacked either this is rob dog lol," he added.
Kylie has since changed her phone number, while Chyna informed fans on Snapchat that her baby shower will be held this Sunday.
Only time will tell if her future sister-in-laws will be in attendance! For more Kardashian feuds, check out the gallery below!
