It seems things may still be fraught between the Kardashian-Jenner family and Rob Kardashian's fiancee Blac Chyna.
Furious Keeping Up With The Kardashians star Rob Kardashian appeared to post half-sister Kylie Jenner's phone number online on Monday night.
It was first thought his account had been hacked but it then came to light that Rob may have actually done it as his family had not invited Blac to the baby shower they had planned for him.

Alongside the telephone number, a message read: "I ain't hacked either this is Rob Dog lol."
A few minutes later, he added: "Didn't invite the Mother of my child to a baby shower you were all trying to throw for me!!? You must have lost your damn minds…"
The number Rob tweeted is now said to be unavailable and Kylie has not responded to her half-brother's messages.
The Kardashian-Jenners and Blac Chyna have made no secret of the fact they have not got along in the past.
Chyna previously dated Kylie's current rapper boyfriend Tyga and Blac didn't hold back when it came to voicing her disgust at their blossoming romance.
Chyna is said to have previously "followed Kylie around and harassed her", according to TMZ.
And the Kardashian-Jenners weren't exactly on board when Rob first started dating Chyna, with his sister Khloe Kardashian even kicking her brother out of her house.

But Rob found happiness with Chyna who appeared to bring him out of his shell after he retreated from the spotlight.
He recently said during a radio broadcast of On Air With Ryan Seacrest: "I couldn’t really feel comfortable about talking to any of my family members obviously about the situation. It was very, very complicated.
"But my happiness outweighs everything honestly at that point in my life."
He added: "Sometimes your family can’t get you out of the worst place that I was in. I needed an outsider to help me. I couldn’t do it all myself. Chyna helped me through my rough time.
"I was uncomfortable in my skin, just trying to get over that uncomfortable feeling. She really helped me get past that (feeling of) being judged."
