LOS ANGELES -- Britney Spears' car was impounded after police found it abandoned on the street.

Police said Spears was driving Monday night when she had a flat tire on Sunset Boulevard sometime before 8 p.m.

"She left it unattended, and it was blocking traffic, so it was towed," officer Karen Smith, a police spokeswoman, said Tuesday of Spears' car.

Police said it was unlikely the 26-year-old pop star will be ticketed because the car was disabled when it was left in the street.

"She probably will have to pay to get her car out of the impound lot," Smith said.

Spears was hospitalized last week after an hours-long standoff at her home that was triggered by a custody dispute with ex-husband Kevin Federline over the couple's two young sons. A court commissioner took custody of her children from Spears the next day.

The singer has had a series of problems involving her car in recent months. In October, she ran over a photographer's foot.
