Britney Spears has filed a restraining order against her mother. The singer asked her lawyer last week to complete the paperwork necessary to keep her mother, Lynne, away from her two sons. Spears explained that her mother is abusing prescription medication and should not be allowed to see her two grandsons. The star was also furious when she learned that her mother had visited Sean Preston and Jayden James at the home of her ex-husband, Kevin Federline. Spears believes that her mother and Federline forced her into a rehabilitation centre for treatment of an alcohol dependency and post-natal depression. Spears also believes that her mother took Federline's side during her divorce and custody battle. |
