Rapper Tyga's luxury car has been impounded by police after his fiancee, model Blac Chyna, was caught allegedly driving the vehicle without a licence.

Cops received complaints about a matte black Rolls Royce Phantom being driven erratically around Malibu, California on Sunday (13Jul14) and when officers pulled the vehicle over, they discovered Kim Kardashian's close friend Chyna did not have a permit to be behind the wheel.

The $300,000 (£176,470) car was seized and towed away and authorities have only agreed to release the Rolls Royce to a licensed driver, according to Tmz.com.

Former stripper Chyna began dating Tyga in 2011 and they became engaged in 2012. They are parents to a baby boy named King.
