The father of troubled pop star Britney Spears will retain control over her affairs for at least three more weeks, a court ruled Thursday.

Jamie Spears was granted “temporary conservatorship” over his 26-year-old daughter’s affairs two weeks ago when she was in a Los Angeles hospital for psychiatric evaluation.

Los Angeles Court Commissioner Reva Goetz Thursday extended that conservatorship until March 10. The action was taken because a psychiatric report on Britney, due Wednesday, had not yet been submitted, People.com reported.

In another development, Spears’ brother Bryan, 30, and Los Angeles attorney Ivan Taback were named co-trustees of the singer’s trust. Trust funds are used to pay for Britney’s security, medicine, food and other expenses, court papers said.

but only if the singer’s mom, Lynne gives the go-ahead first, it has been revealed.

Britney’s mom is currently looking after Sean Preston, two, and one-year-old Jayden James, while Federline  attends New York Fashion Week with the likes of P Diddy.

A source said: “K-Fed and Lynne get on really well. He hopes Lynne can bring Britney round to see sense so that she can have some face time with her kids.

“He knows however dazed and confused Brit gets, she’ll always love those two kids with all her heart.”

Meawhile, the Toxic singer’s dad has been given the power to sack the star’s manager.

A Los Angeles court granted Jamie Spears’ request to fire Britney’s business manager Howard Grossman during a hearing on Thursday, in which he requested additional powers over his troubled daughters affairs.

Jamie Spears took control of Britney’s money and assets after his daughter was committed into a psychiatric ward at the UCLA Medical Center in Los Angeles last week.

Britney’s parents reportedly dislike Grossman because of his close-relationship with the star’s self-proclaimed manager Sam Lutfi, who they claim drugged their daughter.

Documents released Friday show Grossman was served with the legal documents on Thursday afternoon.

In the papers Los Angeles Superior Court commissioner Reva Goetz ordered Howard Grossman to ‘turn over all documents, records and assets relating to Britney Spears.’

The order came after Goetz held an emergency closed-door hearing brought by Jamie Spears and lawyer Andrew Wallet, who is part of Britney’s conservatorship.

Under the powers of the conservatorship order, Jamie Spears is able to restrict the visitors Britney receives and has the right to approve contracts.

Spears parents hope the measures approved by the court will allow them to calm the craziness that has surrounded the pop star.

Britney discharged herself from the UCLA Medical Center in Los Angeles on Wednesday February 6 after doctors ruled she did not pose a danger to herself or to others.

After leaving she was pursued by crowds of paparazzi and television helicopters on a wild chase around Los Angeles before meeting up with her British pap boyfriend Adnan Galib.

The decision by doctors to let Britney leave the mental health facility infuriated the star’s parents.

In a statement they said: “As parents of an adult child in the throws of a mental health crisis, we were extremely disappointed this morning to learn that over the recommendation of her treating psychiatrist, our daughter Britney was released from the hospital that could best care for her and keep her safe.

“We are deeply concerned about our daughter’s safety and vulnerability and we believe her life is presently at risk.”

“There are conservatorship orders in place created to protect our daughter that are being blatantly disregarded.

“We ask only that the court’s orders be enforced so that a tragedy may be averted.”

 celebrity and heiress Paris Hilton expressed sympathy for her friend Britney Spears while at the premier of her new movie The Hottie and the Nottie. Paris felt bad that Spears, who is currently in hospital, was not able to attend the event. “I feel bad for Britney, she’s a lovely girl,” the New York Post reported Paris as having told PageSix.com.”I wish she was here tonight. I hope she gets well soon!” she added. Adrian Grenier, who was Paris’ man for the night, also added his sympathy for Britney. “Hollywood” is a tough town. Britney’s has it tough I feel sad for her,” he said. However the pair did not let Brit’s no-show damper their spirits for long and they were soon seen grooving on the dance floor.

A Superior Court commissioner gave Britney Spears’ father the power to fire the singer’s business manager, according to documents released Friday.

Commissioner Reva Goetz also ordered Howard Grossman to turn over “all documents, records and assets relating to Britney Spears” to James Spears, who is the court-appointed conservator of his daughter and her estate.

The order came the day after Goetz held an emergency closed-door hearing on a motion brought by the singer’s father and lawyer Andrew Wallet, who is part of the conservatorship.

Spears’ parents said they feared their daughter’s life was at risk after she was released from a hospital psychiatric ward on Wednesday.

Lawyers for Britney Spears’ parents returned to court Thursday for a hush-hush hearing to deal with the troubled singer’s affairs.

The session in Los Angeles Superior Court was closed to the public, and a court spokesman said the proceedings were sealed. But several media reports said that Spears’ father, Jamie Spears, and a court-appointed co-conservator were hoping to strengthen control over Britney’s affairs.

Neither Spears nor her parents attended the hearing. The deranged diva was represented by a court-appointed attorney.

Lawyer Adam Streisand, who met with Britney on Wednesday after she got out of a mental ward, said Thursday he was off the case because the court “had issued orders that prevent Ms. Spears from retaining counsel of her own choosing.”

A day earlier, after Spears, 26, left the mental ward at UCLA Medical Center, her parents said their daughter was in the middle of a mental crisis, and they believe her life is at risk.

“As parents of an adult child in the throes of a mental health crisis, we were extremely disappointed…to learn that over the recommendation of her treating psychiatrist, our daughter Britney was released from the hospital that could best care for her and keep her safe,” said the joint statement released on behalf of the singer’s father and her mother, Lynne Spears.
