Spears granted joint custody of sons

Britney Spears has been granted joint custody of her sons.

According to TMZ, a Los Angeles Superior Court judge has extended an order which was originally put in place during Spears's recent 'Circus' tour.

The agreement states that the singer can travel with Sean Preston, 4, and Jayden James, 3, but must provide her ex-husband Kevin Federline with a place to stay if he wants to join them.

Spears will reportedly get a minimum of 50/50 custody, but will sometimes be granted further access to her sons.

Meanwhile, Federline will allegedly receive between $20,000 to $25,000 (£12,489 to £15,611) whenever the boys are outside California.

The money is in addition to the $20,000 in child support that Spears pays every month.

The judge will review the arrangement at the end of the year.
