Blac Chyna Says Don't Call Me Angela Kardashian ... Until the Money's Right

EXCLUSIVE

Blac Chyna is not cutting the Blac out of her life anytime soon, and the only reason she's legally locking down her Kardashian name is to block squatters.

Sources close to Chyna tell us she wanted to make sure nobody else could cash in on her married name -- so she filed the docs to secure "Angela Renee Kardashian." 

We're told BC is proud of the brand she's built, but realizes "Mr. and Mrs. Kardashian" might get better biz offers in the future than Blac and Rob -- and she wanted to have her ducks in a row if that becomes necessary.

She's already thinking like her in-laws ... we're told Chyna's inspiration was Kim -- who trademarked Kim Kardashian West when she married Kanye.
