London, Oct 23 : Pop star Britney Spears is controlled by her father Jamie, says friends.

Jamie, who took charge of Britney's personal and financial affairs after her emotional breakdown in January 2008, is so determined to keep his daughter under control that he is systematically firing her staff so she doesn't have the chance to get close to anyone.(IANS)
