Britney's dad says he's underpaid

London (ANI): Britney Spears father Jamie Spears has demanded cash for looking after the popstar during her battle with a string of problems. Jamie has asked the court for 5,000 pounds in lost earnings for looking after the 26-year-old when she was battling drinks, drugs and weight problems along with her custody for her two sons. Britney's father was a chef and had to leave his job when he was made a conservator of her estate in February. Jamie's application was approved this week by an LA court and granted him compensation of 1,300 pounds per week for loss of earnings in February.
