Lindsay Lohan, who has a new movie coming out this summer, was arrested several hours ago in Santa Monica. The 21-year-old actress was recently released from rehab, but she was arrested on suspicion of drunk driving and possible possession of cocaine, though this is unconfirmed. Allegedly, Lindsay was involved in a car chase with the mother of an assistant and refused a sobriety test at the scene of her arrest, on Main Street. Lohan has been booked on two counts of misdemeanor and two felonies (transportation and possession). Lohan was released early this morning after posting a twenty-five thousand dollar bond. There were no passengers in Lohan’s vehicle. This arrest comes on the heels of a DUI charge in Beverly Hills, where Lindsay reportedly turned herself in for Memorial Day events involving a hit-and-run.
