Blac Chyna Sued for Not Paying Her Rent

Blac Chyna's landlord has major beef with her for allegedly bailing on her lease 5 months early, and even worse ... NOT paying a dime since she bolted.

Chyna just got sued by the landlord for a home in Studio City, CA that she'd been renting since April 2017. In the suit, the landlord says Chyna's lease called her to be there through March 2019 ... but for some reason, she upped and moved back in November 2018.

We're guessing he wouldn't care about her leaving IF she paid the remaining rent. Well, guess what? According to the suit, Chyna owes $55,546 for about 5 months of rent. The landlord subtracted her $25k deposit, but tacked on $18k in damages -- he claims she removed "fixtures and equipment" from the pad.

All told, Blac Chyna is $48,546 in the red ... according to the docs, obtained by TMZ.
