Earlier this month, Gordon said Spears engaged in "habitual, frequent and continuous use of controlled substances and alcohol" and ordered her to undergo random drug and alcohol testing twice a week as part of her ongoing custody dispute with Federline.

Spears also was previously ordered to meet weekly with a "parenting coach" who was to observe and report back to the court about her parenting skills. Both Spears and Federline must complete the court's "Parenting Without Conflict" class. Spears and Federline were married in October 2004. She filed for divorce last November and it became official in July.

Britney Spears failed to provide two weekly drug and alcohol random tests. The judge may have felt that by taking away her children Spears would understand the severity of the situation and refrain from using drugs and alcohol.
