Running the life and career of Britney Spears is a tough job, but somebody's gotta do it. And since a court ruled in 2008 that she was not fit to, her father, Jamie Spears has stepped in. Jamie has overseen Britney's life pretty much without complaint for more than five years, but now, Breaking Celebrity News has learned, he's asking for more money! Court documents obtained by Breaking Celebrity News expose what Jamie's been paid for taking care of his daughter, and what his demands are going forward.

"I continue to perform services to protect and care for Britney's person and to administer her estate in good faith and in her best interests," Jamie writes in a new petition that was filed on October 15 in L.A.

He reveals, "I continue to have significant oversight duties relating to her visitation with her children."

From the beginning, Jamie's been paid $16,000 per month for those duties, and is now asking the court merely to extend that compensation.
