Britney Spears dumped by manager as judge rules she must undergo twice-weekly random drug testing

Britney Spears' has confirmed he is no longer working with the troubled star as a judge rules she will be subject to twice-weekly alcohol and drugs tests.

Following on from yesterday's revelations from Spears' ex-bodyguard about the star's drug use, the Los Angeles Superior Court Commissioner Scott Gordon announced 'there is a habitual, frequent and continuous use of controlled substances and alcohol by (Spears)', and ordered that she undergo twice-weekly random drugs testing.

On top of this, both Britney and ex-husband Kevin Federline have been ordered not to consume alcohol or non-prescription controlled substances at least 12 hours prior to being with their children.

Britney will also be required to meet with a parenting coach at least twice a week for a total of 8 hours, and the commissioner ordered both Spears and Federline to complete a programme called Parenting Without Conflict - enrolling by the end of the week.

Kevin is seeking primary physical custody of the two children - Sean Preston, 2, and one-year-old Jayden James - but the current custody arrangement of 50-50 has not yet changed.
