LATEST: Britney Spears has applied for a California driver's license following the news she has temporarily lost custody of her children. The troubled pop star, 25, handed over sons Sean Preston, two, and Jayden James, one, to Kevin Federline on Monday (01Oct07). She then drove with a friend to a Department of Motor Vehicles office in Van Nuys, California. There, Spears filled out paperwork and took a written test. DMV regulations do not require a behind-the-wheel test. Last month (Sep07), the singer was charged with misdemeanour driving without a valid California license. According to the DMV, Spears had never been issued a California license, despite having homes in Los Angeles for years. The state requires people to apply for a license within 10 days of residence. Records show that Spears does have a Louisiana license valid through to December 2009.
