Britney Spears blows $61m in 1 year

Britney Spears has blown $61m this past year, it has been revealed.

The troubled singer's father -- who was named co-conservator of her estate on February 1 -- made the discovery after going through her books.

"It's staggering how much money has been used up," a Spears family friend says.

The 'Toxic' hitmaker has been forced to shell out a fortune on expensive legal bills, rehab and psychiatric care, as well as losing money due to her inability to work since her infamous head shaving incident in February 2007 and her admittance into a psychiatric ward earlier this year.

Robert Bianchi, an LA-based CPA who isn’t an accountant for Britney, said: "By not touring for her last album [Blackout], she lost out on $50 million."

Jamie Spears hired his own accountants to examine Britney's accounts, and bring an end to the 26-year-old’s excessive spending. "It’s been quite a challenge getting things under control," the insider says.

"She's spending about a fifth of what she used to," the insider adds to In Touch Weekly.
