Talk show host Wendy Williams hit a sore spot with Blac Chyna during a segment on her show Friday. Wendy ranted about Rob Kardashian lacking confidence and being taken advantage of by Chyna and her mother for money and fame.

Needless to say, Rob’s pregnant fiance wasn’t happy. Blac Chyna posted a less than flattering picture of Wendy on her Instagram and let her have it in the caption. She raged:

“You go out there talking about my family like you just hit the pipe backstage! When I decided to do this show I knew I would be letting the world see us. But your horse face a-- woke up on the wrong side of the stable and decide to go overboard with your f--k boy comments.”

Chyna is set to give birth next week at the luxurious Cedars-Sinai Medical Center in Los Angeles. It’ll cost around $4k a night according to TMZ. Whatever she’s doing with Rob is clearly paying off.
