Britney Spears must provide drug lab with one good phone number

LOS ANGELES -- Britney Spears must provide a single, working telephone number to be called in for drug testing, a court commissioner ruled Thursday after her ex-husband's attorney said she has repeatedly failed to respond to calls for the court-ordered screenings.

Of 14 such calls placed to Spears, she failed to respond eight times, Federline attorney Mark Vincent Kaplan told Superior Court Commissioner Scott Gordon.

Spears lawyer Anne Kiley argued that Spears hadn't responded within an hour, as ordered by the court, because she was sleeping, and asked that she be given a six-hour time-frame. But Gordon said time wasn't the problem, noting Spears had lost telephone numbers and changed numbers.

"There needs to be one number that the testing facility calls that she responds to," Gordon ruled. He added that she can change phones, as long as everyone involved is notified.

Federline, 29, and Spears, 25, were not in court for the hearing. After a break, Gordon issued his ruling, adding that he was not going to make any further modifications to existing custody orders.

Under those orders, Federline has temporary custody of Sean Preston, 2, and Jayden James, 1, because Spears has defied court orders. Spears gets one overnight visit and two daytime visits a week. A court-appointed parenting coach, a childproofed home and car restraints were all written into the orders.

Attorneys for Spears and Federline, married in October 2004, have repeatedly been in court about custody since they split. Their divorce was final in July.
