Lil Twist cited for birthday boy Bieber's tinted windows

Justin Bieber's pal Lil Twist celebrated his friend's 19th birthday with a traffic ticket - from behind the wheel of the pop star's luxury sports car.

The rapper, real name Christopher Lynn Moore, was pulled over on the 101 Freeway by California highway patrol officers, who caught him making an unsafe lane change in Bieber's Fisker Karma on Friday (01Mar13).

TMZ.com reports Twist got away with a ticket for improper driving, but the cops cited him for Bieber's illegally tinted windows.

The car has been nothing but trouble for Bieber since he was handed the keys for his 18th birthday a year ago - the singer was booked for speeding on the 101 Freeway as he attempted to race away from the paparazzi last year (12) and Twist got a ticket in January (13) when he was behind the wheel.

Bieber is currently celebrating his 19th birthday on tour in London.
