Britney Spears has been ordered to read the Bible for an hour a day.

The "Womanizer" singer's father Jamie - who as co-conservator of her estate has full control of Britney's affairs - has issued the star with a string of rules to ensure she doesn't go off the rails on her "The Circus Starring Britney Spears" tour.

A source told Britain's Daily Mirror newspaper: "Jamie is determined nothing can go wrong with Britney's comeback. He's making sure she reads the Bible for at least an hour during her quiet time before she goes on stage and has banned her from using the internet. He is even monitoring what she eats by insisting on none of her beloved junk food on the rider.

"He's stopping her from leaving her hotel unless accompanied by a security guard and even though she gets on much better with her ex-husband, Kevin Federline, she isn't allowed to speak to him without Jamie or her manager there."

Despite Jamie's strict orders, it seems as if his daughter - who was hospitalised last year following a breakdown - has already found a way to flout his rules.

Fans at her show in New York last week were stunned to see the toned torso she had showed off on the opening night of her tour in Louisiana has already disappeared.

Despite her energetic dance routine, the 27-year-old-star had a roll of fat hanging over her skimpy belly-dancer costume as she performed "Me Against The Music".

One fan said: "Britney moves around loads on stage but she's clearly carrying extra weight - perhaps someone should think about altering her costumes."
