Britney Spears has lost custody of her children, some say she is losing her mind, and now she has officially lost her car.

The troubled pop star's white Mercedes was impounded last night after she got a flat tire while driving around the streets of Los Angeles.

Britney, who has one of her biggest meltdowns yet last week and has subsequently lost all visitation rights with her children, simply left her car in the middle of the road in Brentwood when she could no longer drive it.

Lt. David Drimes from the L.A. Police Department said, "Ms. Spears's car was impounded. Officers on the scene told me it was blocking the roadway and that it was unsafe enough to leave at the location."

Britney spends a majority of her nights cruising around the streets, with paparazzi trailing her. She has photo opportunities in gas stations and hotel entrances, before retreating to one of her many homes.

However, the flat tire didn't stop Britney from her unusual routine. A paparazzi photographer dropped her and her assistant, Carla, back at the pop star's mansion. She then returned to the road in a Toyota Camry.
