Pop singer Britney Spears did not regain permission to visit sons Sean Preston and Jayden James during a closed-door court hearing on Tuesday, after lawyers for both sides reportedly could not agree on the terms.

Britney Spears, who once started out as a Mouseketeer in the Disney Channel series The New Mickey Mouse Club, as a pre-teen, is now a Grammy winning multi-platinum singer who’s fallen, hopefully just temporarily, down a bizarre rabbit’s hole.

The 26-year-old mother of two divorced backup dancer Kevin Federline in July 2007, after a 3-year marriage, with the couple sharing legal and physical custody of sons Sean Preston, 2 and Jayden James, 1.

Britney went through a well-publicized chaotic whirlwind of strange behavior afterwards and ultimately lost primary custody of the boys in October. After the Jan. 3 standoff with police, when she refused to hand over the children to Federline at the scheduled time, Britney lost visitation rights as well.

Britney has not seen her sons since then. At the time, she was hospitalized at Cedars-Sinai Medical Center for two days. Later that month, she was placed on a 5150 Involuntary psychiatric hold for a second time, and admitted at the UCLA Medical Center’s psychiatric ward. She left after six days.

Tuesday’s court hearing was a lengthy one according to reports, yet no consensus was reached between lawyers for the two sides.

Los Angeles Superior Court spokesman Alan Parachini told reporters that no change had been ordered by the family judge regarding Britney’s interdiction to see the boys. A request for a gag order from Britney’s lawyer was denied by the court, thus allowing attorneys to talk to the media.

Another request was granted though; Britney can change her lawyer, Anne Kiley of Los Angeles-based firm Trope & Trope, with new attorney Stacy Phillips.

Jamie Spears, the singer’s father, was named temporary co-conservator of her estate, along with attorney Andrew Wallet, on Jan. 31, by Superior Court Commissioner Reva Goetz. The conservatorship was to be discussed once more on Feb. 14; because a medical evaluation of Britney was delayed, her father’s co-conservator status was extended further.

Mark Vincent Kaplan, Kevin Federline’s attorney in the custody case, who hinted last summer that the children would be “safer” with their father, told People magazine Wednesday that it is Federline’s desire for the situation to be resolved.

“We all want this as soon as possible,” Kaplan said referring to Britney regaining visitation rights once more. “That's Kevin's desire – to have his kids visiting their mother. That's everyone's goal in this case.”

Kaplan also told People magazine that Jamie Spears’ presence in his daughter’s life is very welcome and that it could even make it possible “to develop a visitation plan that enables these children to have a mother in their lives.”

Britney is reportedly receiving treatment for bipolar disorder. Her recent public appearances, shopping with her mother or having dinner with her father, have shown her more composed and healthy-looking than she has appeared in a long time.
