Blac Chyna threatens to sue TikTok star over sex-trafficking claims

Black China denies charges of kidnapping and sex trafficking Ava Louise … she says the claims are just a desperate attempt to increase the TikTok star’s fan base.

BC had her lawyers write Ava a cease and desist letter after the social media star recently uploaded a series of TikTok posts in which she accused Chyna of holding her hostage and trying to pimp her.

In a legal letter obtained by TMZ , Chyna says everything Ava claims is “false, extreme and outrageous” … and her lawyers are demanding that she cease and desist immediately … or face legal consequences.

Blac Chyna’s legal team is also targeting Ava’s reputation … they say it’s part of “threatening and outrageous behavior” to expand Ava’s social media platform, saying Ava previously admitted to making up false rumors about Kanye West chat with YouTube beauty gurus Geoffrey Starr.

It should be noted … Kris Jenner threatened Ava with legal action last year after Ava said she received a cease and desist letter from Chris’ company threatening legal action if she didn’t drop the allegations Kim and Kanye.

Chris’s camp says they never sent Ava such a letter and that her story was made up.
