Los Angeles, Aug 22 (IANS): Singer Britney Spears is allegedly "fed up" of her father Jamie Spears controlling her finances.

The 32-year-old's personal and professional affairs have been controlled by Jamie and Andrew Wallett since 2008, but she wants the conservatorship to come to an end, so she is free to marry her boyfriend David Lucado, reports femalefirst.co.uk.

"She's so sick of all the bodyguards. And she wants to be out from under her father's thumb. Her relationship with David has never been stronger. She also wants the conservatorship to end, so she can be free to marry him," said a source.

But her friends apparently don't think she's ready to control her own finances at the moment.

"Even though Britney is doing very well, there are no plans to end the conservatorship anytime soon. Her doctors just don't think she is ready to be on her own yet," said the source.

Britney, who has two children Sean Preston, 8, and Jayden James, 7, with her ex-husband Kevin Federline, was placed under permanent conservatorship after she was admitted to Ronald Reagan UCLA Medical Center and put on involuntary psychiatric hold in 2008.
