As you've no doubt heard by this point, Rob Kardashian is in the midst of one of the worst public meltdowns in recent memory.
One that all boils down to the mother of his child, Blac Chyna.
The 30-year-old Rob went off on Chyna in an appalling social media tirade that stunned fans and may land him in legal trouble.
Earlier this week, Chyna was granted a restraining order as a result of Rob's cyber-bullying, and now it seems she's not his only target.
According to Radar Online, in the midst of his tirade, the troubled Rob posted a tweet that even he realized went too far.
He immediately deleted it, but not before it earned him some new enemies who are powerfully pissed off by his actions.
The site claims that the Keeping Up with the Kardashians star tweeted the following toward the end of his online tantrum:
“My mom keeps telling me to stop, but she was married to a dude named Caitlyn, so I’m def not listening to her."
Needless to say, the remark didn't go over well.
Within minutes the tweet was deleted, either at the behest of Kris Jenner, or because even Rob has flashes of common sense.
Unfortunately for the troubled 30-year-old, insiders say it had already caught the attention of Rob's former stepbrother, Caitlyn's son, Brody Jenner:
“Brody’s never liked Rob, who he sees as a screwed-up punk who’s all mouth and no class,” says one source.
“He’s like, ‘How dare he attack Caitlyn, after everything she’s done for him?’ The whole dig towards his mom for marrying Bruce was revolting."
"He's way out of line.”
Apparently, it's not the first time, either, as Rob has a history of making insensitive comments about Caitlyn's transition.
Says the source:
“(Rob’s) had this coming for a while, with all the sneering and rude comments since Caitlyn announced her transition. But this public attack has crossed the line."
The insider notes that Brody, one of Caitlyn's two sons from his previous marriage, has expressed a desire to physically assault Rob.
He'll probably have to take a number.
In all seriousness, we doubt that'll ever happen (though we hope it ends up on PPV if it does), but the incident serves as a reminder:
Rob has fallen very, very far these days, to the point where he's made countless enemies, even among those closest to him.
Maybe someday he'll be able to turn things around, but it'll require a whole lot of change and self-examination on his part.
