While lawyers were in two L.A. courthouses Monday arguing over her various driving violations and custody issues, Britney Spears spent her time readying for her next musical move: a new video.

Usmagazine.com has learned that production on the video for her single “Piece of Me” is scheduled to begin Tuesday at 8 a.m. at Social Hollywood. A source tells Us that the video will be directed by Wayne Isham, who helmed the video for the 2002 Brit hit, “I’m Not a Girl, Not Yet a Woman.”

A set source tells Us that since Spears, 25, has a scheduled visit with sons Sean Preston, 2, and Jayden James, 1, on Tuesday, she will only be available to film for two hours, between noon and 2 p.m. During that time she will shoot scenes where she dances on a bar and runs down a staircase. There will be 15 extras, as well as a body double for Brit.

Meanwhile, at a hearing in her ongoing custody battle with ex Kevin Federline on Monday, lawyers for both Spears and Federline discussed holiday visitation plans and whether a representative for Child and Family Services should have access to sealed case documents.
Following the hearing, court spokesperson Alan Parachini told reporters: “There was a great deal of interaction over issues that were important to the parties. There was an order made relating to DCFS access to the files. There were extensive discussions over a visitation agreement over the holiday period. Holiday visitation will be different from the existing schedule. There was another matter discussed that I can’t discuss. The next court hearing is January 23.”
