Britney Spears reportedly wants to end her conservatorship.

Control of the 30-year-old singer's affairs was placed in the hands of father Jamie Spears following her 2008 breakdown, and has remained that way every since.

However, Britney - who has sons Sean Preston, six, and Jayden, five, with ex-husband Kevin Federline - apparently feels ready to step back into the driver's seat.

A source said: "Britney has said that she feels she is ready to resume control of her life.

"She has expressed this sentiment on multiple occasions, but her doctor believes that Britney isn't ready for the conservatorship to be lifted. She has come a very long way in the last 18 months especially but her team wants more time.

"She just wants to be able to call her own shots."

But the insider doesn't believe the 'Hold It Against Me' hitmaker will get her own way any time soon, despite her engagement to former manager Jason Trawick and a possible 'X Factor' deal.

The source continued: "It looks like it won't be ending anytime soon, but Britney feels that she is powerless to fight it.

"She has been on two wildly successful worldwide concert tours, has gotten engaged, and is now in talks to join a major television show, what more does she have to do to prove to people that she is ready to resume control of her life?

"Britney has been told Jamie's lawyers could petition the judge for the conservatorship to end later this year, and not anytime sooner."
