Britney Spears appears to hit paparazzo

Hours after losing child-visitation rights Thursday, the troubled pop star apparently ran over a photographer's foot with her car.

According to celebrity Web site Hollywood.TV, Spears was pulling out of a Beverly Hills medical building around 5 p.m. when the incident occurred.

Messages left late Thursday with Spears' attorney were not immediately returned. A police dispatcher in Beverly Hills said late Thursday no police report had been filed.

Video on the Web site is titled "The Unfortunate Foot Incident," but doesn't show the tire of Spears' car rolling over the cameraman's foot.

The video shows Spears beginning to pull out of a parking garage when her car is surrounded by more than a dozen photographers. The car comes to a stop.

Spears honks and the car lurches forward a few feet. Shouting is heard, and the camera jerks around as fellow photographers apparently help a man to his feet.

Spears drives off. Seconds later, the video shows what appears to be a tire mark on the unidentified paparazzo's sock. The man, wearing sandals with white socks, doesn't respond to questions from the cameraman and walks off without any apparent problems.

Earlier Thursday, Spears learned she was barred from visiting her young sons, who are in the custody of ex-husband Kevin Federline, until she complies with a court order, Superior Court Commissioner Scott Gordon ruled.

The order, dated Wednesday, does not spell out what directives Spears defied. A hearing in the matter was scheduled for Oct. 26.

Spears' apparent foot bender isn't the first time she's had trouble behind the wheel. She faces hit and run charges and driving without a valid license from an Aug. 6 wreck.

In that crash, paparazzi filmed Spears steering her car into another vehicle as she tried to turn into a spot in a Studio City parking lot. The video showed her walking away after assessing the damage to her own car.
