Jamie Spears: Working on Behalf of Britney Spears 24-7

Britney Spears' father, Jamie Spears, has quit his catering job to dedicate himself full-time to overseeing the pop star's affairs, court papers show.

As a result, Jamie Spears was given $10,000 in back pay to cover the first month of his co-conservatorship of her estate, which started February 1.

He was awarded a $2,500 weekly salary beginning in March.

"The responsibilities he has assumed as conservator ... have required [his] full-time attention," says the request for "replacement compensation."

"As a result, he has been unable to continue to his prior employment and he has lost his source of income which he needs to pay his living expenses."

Jamie, unlike Britney's mom Lynne Spears, never cashed in on his daughters and was making a modest $50,000 a year before coming to Brit's rescue.

Since Jamie Spears took over his daughter's personal, professional and legal affairs, the singer has secured expanded visitation with her two sons, who live with Britney's ex-husband, Kevin Federline.

Sean Preston, 2, and Jayden James, 1, have birthdays in September.
