The mother of two posed in a black sequin gown with a plunging neckline and a bold thigh-high slit, lying on the rug next to her bed in several seductive stances.
Her fiancé, Rob Kardashian, even shared one of the pics to his own Instagram account.
The sultry new photos came just as news broke the Rob’s family has filed a notice to block Chyna’s application to trademark the name Angela Renee Kardashian, which would be her married name.
The application was filed on behalf of Chyna’s company Lashed LLC and was opposed by Kim, Khloe, and Kourtney Kardashian’s companies.
According to the documents, obtained by ET, the Kardashians say that their name and brand has "acquired distinctiveness and goodwill in the United States and throughout the world," and that each of the sisters' companies have "spent, and continue to invest, a substantial amount of time, resources and money in protecting, advertising and promoting" their brand.
Rob has yet to publicly respond to the lawsuit.
