LOS ANGELES - There could be more trouble ahead for Britney Spears in her custody battle.
Kevin Federline's lawyer says he may try to subpoena video footage that apparently shows the pop princess running a red light at Hollywood Hills intersection while driving with her two young sons in the back seat.
Attorney Mark Vincent Kaplan says he is weighing whether to seek a subpoena from the court Wednesday for the footage, which was posted on the celebrity news website TMZ.com. Separately, TMZ reported that it was contacted by Kaplan.
Kaplan declined further comment but the footage could support his request to a Superior Court commissioner to stop Spears from driving when her sons are in her car.
Federline has temporary custody of Sean Preston, 2, and Jayden James, 1, because Spears has defied court orders.
A message left for an attorney for Spears, Anne Kiley, was not immediately returned Monday.
Spears' driving has been an ongoing problem for her.
In 2006, she was photographed driving with Sean Preston on her lap and authorities visited her home to investigate.
Last month, she pleaded not guilty to a misdemeanour charge of driving without a valid driver's licence. A misdemeanour hit-and-run charge from an August parking lot crash was dismissed after she paid an undisclosed amount to the car's owner.
Spears, 25, and Federline, 29, were married in October 2004. The two have wrangled in court over custody issues since they split. Their divorce was final in July.
