Blac Chyna has added Khloe Kardashian and Kylie Jenner to her lawsuit against former fiance Rob Kardashian and various members of his family

According to TMZ, amended documents don't reveal why Khloe and Kylie have been added back to the lawsuit alongside Rob, his mother Kris Jenner and half-sister Kim Kardashian West but claimed one of the sisters had branded her "toxic".

She accused one unspecified member of the family of saying: "The show ['Rob & Chyna'] is giving this toxic woman money and exposure she lives and breathes for and by continuing it ... [s]he will proceed with using and physically abusing my brother."

The amendment came after Chyna previously accused the 'Keeping Up With the Kardashians' star of trying to destroy her career and "coming after" her after she split from Rob.

Her court documents stated: "The unwritten rule no one told (her) when she began her relationship with Kardashian is that the entire family will come after you if you leave, using their fame, wealth and power to take you down, including getting your television show cancelled (despite great ratings), spreading lies about you, and even funding a bogus lawsuit about a crumbled gingerbread house."

But the family previously moved to throw out a lawsuit filed by Chyna regarding 'Rob & Chyna', after they claimed the only reason the show was axed was because Chyna got a restraining order against 30-year-old Rob.

Their filing stated: "Given Plaintiff's conduct in seeking and obtaining a restraining order that required Rob to stay away from Plaintiff and her workplace, no trier of fact could possibly find that it was reasonably probable that a second season of 'Rob & Chyna' would have been picked up and filmed."

Previous court documents filed by Chyna - whose real name is Angela White - accused the entire Kardashian family of interfering with the shooting of the couple's reality show.

Her filing stated: "Rob Kardashian is an abuser intent on destroying Angela White, the mother of his baby, who left him in 2016. In revenge, the Kardashian-Jenner family became media predators, slut-shaming her on social media and killing her hit television show, which had already begun filming a second season.

"Rob Kardashian and his powerful, vindictive family have done enough damage to Ms. White's career and professional reputation, which she singlehandedly built from scratch - without the help of a famous last name. This lawsuit seeks to hold them accountable."
