Britney Spears is reportedly set to add a string of dates to the U.K. leg of her CIRCUS tour - after her dad JAMIE urged her to perform more concerts.
The pop superstar is allegedly considering more gigs after Jamie pointed out her popularity is currently so high she should try to cash in.
But the Toxic hitmaker is said to be resisting the plan to increase her British road trip as she is struggling with the gruelling schedule.
Spears' father was made conservator of her affairs after her 2008 meltdown which led to the singer being taken to hospital for psychiatric evaluation.
A family friend tells U.K. magazine Reveal, "Jamie can't physically force Britney to get on stage and do more concerts, but he does have nearly all the power. He controls the purse strings and can make things very difficult for Britney if he chooses to.
"He gets to dictate her schedule - where she goes, who she sees, who she doesn't see. He's in charge of everything to do with her life. It's a battle of wills over who will win - but while her dad remains in charge, he'll be laying down the law."
