Lord Disick have mercy on us all.

Mere days after Rob Kardashian savagely tweeted out his sister Kylie Jenner's phone number for nearly 6.7 million followers to see, he got a taste of his own petty medicine when his fiancee, Blac Chyna, did the same thing to him.

On Thursday evening (September 29), Chyna put Rob on blast publicly, not only sharing his phone number on Twitter, but addressing it in a video on Snapchat afterwards where she announces, "To ensure your man is not texting no b---hes, just tweet his number out. How’s that feel, Rob? How you feel?"

Rob, who is also in the video, laughs uncomfortably in response.

"It’s good," he replies, as his phone can be heard chiming with message notifications.

"Get your number changed. Thank you!" she snaps back.

In another video clip, Chyna continues: "Since all these females want to keep texting his phone ‘cause they had his number before, talking about, 'You good? You and Chyna good?' Nah, we good. We good. We good. We straight."

What goes around, comes around: Earlier this week, Rob tweeted out Kylie's number, revealing that the Kardashians had apparently not invited Chyna to the baby shower they were throwing the Rob & Chyna couple.

"Didn’t invite the Mother of my child to a baby shower you all were trying to throw for me?" Rob tweeted. "You all must have lost your damn minds."

Later, a source told Entertainment Tonight that the whole thing was just a misunderstanding and that Chyna simply couldn't make it to the shower, but had given the Kardashian-Jenner girls the thumbs-up to move forward with the original date for Rob.
