Justin Bieber is facing more bad news after his pal Lil Twist reportedly smashed the pop star's luxury sports car.

The rapper, real name Christopher Lynn Moore, was behind the wheel of Bieber's Fisker Karma when he allegedly crashed into cement poles in a parking lot in San Fernando Valley, California on Tuesday (05Mar13).

According to Tmz.com, another driver pulled up a few minutes later to take Lil Twist and his passengers away, leaving the Fisker behind.

The incident caps a difficult week for the Baby hitmaker, who collapsed at his concert in London on Thursday (07Mar13).

The singer, who turned 19 last week (01Mar13), also had his birthday celebrations ruined following a dispute with the owners of the nightclub where he planned to host his party, and he caused uproar on Monday night (04Mar13) by arriving late to his gig at the O2 Arena.

To top it off, Lil Twist landed a ticket last week (01Mar13) while borrowing the Fisker Karma - cops cited him for Bieber's illegally tinted windows.
