Blac Chyna has just taken things to the next level as she has added Khloe Kardashian and Kylie Jenner to her lawsuit against former fiance Rob Kardashian and various members of his family.

The 29-year-old reality star has accused various members of the Kardashian/Jenner clan of conspiring to end her TV show 'Rob and Chyna' and, after previously dropping the 'Revenge Body' host and the lip kit guru from her legal case, she's now added them back in.

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 Kim Kardashian West but it’s claimed one of the sisters had branded her "toxic" – OUCH!

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.

We hope this lawsuit dosen’t get more nasty!
