A video believed to show Britney Spears running a red light was submitted to a Los Angeles Superior Court on Friday, the latest piece of evidence entered in the child-custody battle between the pop star and ex-husband Kevin Federline.

Mark Vincent Kaplan, Federline’s attorney, declined to comment after the closed-door hearing before Los Angeles County Superior Court Commissioner Scott Gordon. Kaplan also said Gordon issued a sealed order that he could not discuss.

“I can’t tell you what was discussed, I can’t tell you what was in the papers, I can’t even tell you what was in the order,” Kaplan said.

The celebrity Web site TMZ.com reported the video showed the 25-year-old singer running a red light at a Hollywood Hills intersection while driving with the couple’s two young sons in the back seat of her car.

An unidentified witness who had been subpoenaed also appeared briefly at Friday’s court hearing. His testimony was postponed.

The case is due back in court Nov. 26.

Last month, Gordon ruled that Spears could have sleepovers with her two boys if she has regular drug tests, childproofs her home and ensures the children are buckled into their car seats when she takes them on a drive.

He had previously suspended Spears’ custody rights, ruling she engaged in “habitual, frequent and continuous use of controlled substances and alcohol.”
