Britney Spears’ attorney filed a motion to change the singer’s twice-weekly random drug testing at a hearing for her ongoing custody battle with ex Kevin Federline October 26 in L.A. Superior Court, in court papers released Tuesday.

According to the papers, her attorney had filed the request before, but Federline’s attorney opposed it October 25. At their hyped-up hearing Friday, Spears’ attorney filed another request to terminate or modify the court order.

A judge has yet to issue a ruling.

It is the latest update in the ex-couple’s increasingly complicated custody battle.

On September 17, L.A. Superior Court Commissioner Scott Gordon dubbed Spears a “habitual” drug and alcohol user and ordered her to undergo twice-weekly random drug testing. He also ordered Spears and Federline to participate in joint co-parenting counseling. Spears was also ordered to undergo individual counseling at least once a week.

In addition, the pair were required to enroll in a Parenting Without Conflict program (Us reported they attended the first session October 24 at the Beverly Hills Hotel.)

On October 1, Spears, who had up until this point shared 50-50 custody with Federline, temporarily lost of custody because, her attorney said at the time, she was accused of not taking a random drug and alcohol test and and could not provide a California driver’s license.

Spears was granted visits with her boys with a court-appointed monitor October 3. She was then awarded one monitored overnight visit a week October 11.

However, Spears was stripped of visitation rights October 17 because she did not answer her court-mandated cell phone for a required conference call, a source told Us. (The source claimed her Malibu home did not have reliable reception.)

By October 20, Spears had regained visitation rights with the presence of a court monitor.

Spears and Federline are due back in court November 26 — the same day as her hearing for a misdemeanor count of driving without a California driver’s license — where a judge will review a complete report from the court-appointed monitor.
