A court commissioner granted Britney Spears three monitored visits a week with her two small sons while ordering her to childproof her house and work out a schedule for the visits with ex-husband Kevin Federline, according to a ruling made Tuesday. Superior Court Commissioner Scott Gordon also required that Spears undergo random weekly drug and alcohol tests. Spears also must continue meeting with a court-appointed parenting coach, and the children must be in car seats when they are being driven, the ruling states. The ruling came after a three-hour hearing attended by both Spears and Federline. Extensive testimony was presented on a number of issues. Gordon previously said there was evidence that Spears is a “habitual, frequent and continuous” user of drugs and alcohol. He had previously withdrawn approval for her to even visit the children after finding she had failed to comply with some conditions for shared custody. He later withdrew the ban and allowed her to visit her sons, but only in the presence of a court-approved monitor.
