The 26-year-old pop singer, whose career has been buried under an avalanche of personal and health problems, rear-ended a car in stop-and-go traffic after she failed to stop her Mercedes in time, said CHP Officer Patrick Kimball.

The rear-ended car, driven by a man identified as "J. Flint," in turn pushed forward into another car, the CHP collision report said. The driver of the third car observed no damage, and drove off, the CHP incident report said.

Web site TMZ said on Sunday that CHP officers on the scene performed a sobriety test on Spears, which she passed.

Spears is invariably trailed by a large posse of paparazzi while running her daily chores. Photographers were instantly on the scene.
