Jamie Spears -- Britney Is Hard Work

Jamie Spears says taking care of Britney is more than a full time job, and that's why the court is giving him $16,000 a month.

In a declaration to the conservatorship commissioner filed Friday, Jamie wrote that he engages in 200 - 400 communications every day to coordinate all things Brit -- not including Fanta orders. Jamie says he's overseeing Britney's tour that kicks off tonight, and must coordinate Brit's "medical, health, business, costuming, personal, security, household staff, and legal matters (touching upon entertainment, music, family law litigation, the resolution of numerous disputes, and the ongoing litigation and conservatorship matters."
