Rob gets angry, tweets Kylie's phone number

Stand back people because the Kardashian/Jenners are beefing big time!

Yep, Rob Kardashian and his half-sister Kylie Jenner are currently in the ring after Rob tweeted Kylie's phone number to his 6.65million followers.

Why? Because for some reason the family seemingly left his pregnant baby mama Blac Chyna off the invite list to a baby shower they were throwing for him.

"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,' the 29-year-old reality star tweeted.

"Kylie's #... I aint hacked either this is rob dog lol!" he added in a post that still hasn't been removed four hours later.

Rob and Kylie's is a relationship that's been fraught with tension ever since he hooked up with Blac earlier this year.

After all, Blac used to date Kylie's current beau, rapper Tyga. In fact, they've even got a son, King Cairo, together.

However, in a recent chat with People magazine, Blac revealed that while they'd never double date, the vibe between the four was good.

“No [we’re not going to hang out with them], but everyone is super comfortable,” she said. “There’s no animosity. We’ve all talked. I’ve met up with Kylie.

“I feel comfortable with Kylie being around my son, King, and I’m sure Tyga feels comfortable having King around Rob. Everybody is mature. We’re not holding grudges. We’ve moved on.”
