Socialite Blac Chyna dropped a bombshell about her ex-boyfriend and baby daddy Rob Kardashian. In court documents filed by Chyna, whose real name is Angela Renée White, she claimed the portly reality TV star dropped $100,000 on weight loss surgery, but he publicly said he lost the weight due to exercise and diet.

According to the court documents, both Chyna and Rob, 30, underwent weight loss procedures after the birth of their daughter, Dream, but Rob’s procedure apparently failed. The father-of-one is seen below in a photo in 2012.

“In fact, Rob Kardashian himself underwent weight loss surgery that cost $100,000, whereas Ms. White’s surgery was for a lesser amount,” said the lawsuit, obtained by the Daily Mail Online.

The documents also allege that Chyna underwent minor cosmetic surgery, including a breast reduction and “small amount” of liposuction around her belly button.

The documents stated:

“Ms. White is a well-known social media influencer and trendsetter who professionally endorses health, lifestyle, and diet products in her Instagram and Twitter accounts. Accordingly, the manner in which Rob Kardashian revealed Ms. White’s personal medical information jeopardized Ms. White’s endorsement deals with several weight loss, fitness, and diet companies – that all pay Ms. White to promote their products on social media.”

This is the latest lawsuit for the 29-year-old model, who recently filed multimillion dollar lawsuits against the entire Kardashian family following the cancellation of her and Rob’s reality show, Rob & Chyna.
