Rob Kardashian has publicly attacked sister Kylie and released her personal information.

If you read the comments section of any celebrity Instagram post, you’ll come across multiple people claiming to know the most highly sought-after celeb secret.

Their mobile phone numbers.

Most of them can be swiftly ignored as fake, but once in a while, we’re blessed with details that we simply cannot ignore.

Yep, he tweeted it not once, but TWICE.

Sadly, the number has since been disconnected, but not before Rob revealed the reason behind the move.

“Didn’t invite the mother of my child to a baby shower you all were trying to throw for me?” he wrote on Twitter.

“You all must have lost your damn minds.”

Rob and Chyna ???????? E!

Of course, this isn’t the first sign of drama in the family when it comes to Rob’s fiancé, Blac Chyna, who already has a son with Kylie’s boyfriend Tyga.

(Yes, it’s confusing).

Just weeks ago, Rob deleted all trace of his relationship with Chyna from his social media.

Awkward conversations with his sisters regarding his fast-moving relationship with the socialite were also captured on camera for the family’s reality show.
