Blac Chyna sued over friend's car crash

Blac Chyna has been named in a lawsuit after her friend was involved in a hit-and-run accident in her car.

The model, who is pregnant with fiance Rob Kardashian's child, allowed her friend Paige Addison to borrow her BMW in November (15), but Addison allegedly drove past a stop sign and slammed into an SUV, injuring the two passengers inside.

Addison was subsequently charged with a felony hit-and-run.

In the documents obtained by TMZ.com, the unnamed plaintiff claims Chyna should have known Addison was a bad driver, and should have never given her the keys to get behind the wheel.

The plaintiffs are seeking an unspecified amount in medical expenses, lost wages and other damages.
