Lawyers around troubled singer Britney Spears battled in court on Monday over her parenting issues and $1 million in legal bills with one judge ruling the pop star should receive $1,500 a week to spend.

That sum must seem like a small amount for the former child star, who in 2002 was named the world’s No. 1 celebrity by Forbes magazine after earning $39.2 million in one year.

But since 2006, Spears’ life has spiraled downward. She divorced husband Kevin Federline, spent time in rehab, lost custody of her and Federline’s sons, and this year was hospitalized twice for psychiatric evaluation.

In January, her father Jamie Spears won control of her personal and business affairs via a conservatorship, and on Monday Court Commissioner Reva Goetz said he could give Britney a debit or credit card with the $1,500 per week to spend.

Goetz also authorized a $135,000 bank account, controlled by Jamie Spears and a second co-conservator, to pay bills and said conservators could hire an entertainment attorney.

Spears, 26, would appear to need some legal advice because she will appear as a guest star on a new episode of CBS comedy “How I Met Your Mother,” a network spokeswoman said.

A second source close to the show said the episode would tape this week and likely air on March 24, adding that Spears took part in a “table read” rehearsal on Monday.

As a result, Spears was not in court again after missing many hearings throughout 2007 and this year. Her court-appointed attorney Samuel Ingham said he did not know why she was not coming.

Britney Spears’ ex-husband Kevin Federline has agreed to reinstate her visitation rights with their two sons, his lawyer said in a statement on Friday, according to The Associated Press.

Federline’s attorney, Mark Vincent Kaplan, said in a statement the former couple has agreed to a modification of a court order that had stripped Spears of her visitation rights, AP reported. The statement did not provide more details, but Kaplan told People.com on Friday that Spears would be allowed to see her sons “soon, very soon.”

Lawyers for Britney’s father, Jamie Spears, were back in court on Thursday, along with Britney’s co-conservator, however, what exactly went on behind closed doors is unknown.

Court spokesperson Allan Parachini told reporters after the hearing that “everything about this matter is sealed.”

The one thing Parachini did reveal was a motion was filed today by Spears’ co-conservator, attorney Andrew Wallet, which went unopposed.

The nature of the motion is still unknown.

While all of the documents from Thursday’s hearing will remain sealed, court-appointed attorney Sam Ingham told reporters afterwards that what went on this afternoon was “just a small part of the puzzle.”

Britney Spears didn’t have the best year in 2007 - she shaved her hair, paid several visits to rehab, gave a disastrous, now infamous performance at the VMAs - and saw the start of the bitter legal battle between herself and ex-husband Kevin Federline - but it seems the troubled ‘Gimme More’ star will be putting an end to a terrible year by spending New Year’s with her two young sons - and her new paparazzi boyfriend Adnan Ghalib, who, sources claim, happens to be a married man!

A source close to the the Spears family told America’s OK! magazine that Britney and Adnan - who hit the headlines last week when he stayed overnight with the singer in her Beverly Hills hotel room, and her two boys, Sean Preston, 2, and 1-year-old Jayden James, are spending New Year’s Eve at a private beachfront residence near Dana Point, Calif. The source claims that they will also be joined by a court-appointed monitor, responsible for overseeing all of the boys’ visits with their troubled mom.

While Adnan recently claimed that he and Britney were only having “lunch” during their overnight visit, he has been telling a different story to his pals. “He was bragging last week that the night he spent with her at the Peninsula was ‘the best night of his life,’” one insider reveals to the publication.

The insider spoke about the photogs intentions, saying: “He’s always played her knight in shining armor. Not just because he’s a gentleman, but because he’s a true mercenary.”

The source recalls one recent incident where Britney was hiding inside of a locked utility closet in a Target store in Culver City, Calif. “He told me that the reason he talked to her through the door and convinced her to let him escort her to her car was because if she were to leave the store through the back loading dock, he wouldn’t get good photos.”
