Los Angeles ? Britney Spears was derailed yet again in her struggle to get her life back on track, losing custody of her two sons to ex-husband Kevin Federline.

A court commissioner Friday gave sole physical and legal custody of the former couple’s two little boys to Federline and suspended the troubled pop star’s visitation rights.

Spears was hauled away from her home to a hospital by paramedics a day before, after police had to intervene when she refused to return the children to Federline after a court-monitored visit.

Commissioner Scott Gordon ordered another hearing to be held Jan. 14.

Federline had previously been awarded temporary custody of 2-year-old Sean Preston and 1-year-old Jayden James because Spears has defied court orders, resulting in limitations on her visitation.

“I’m not happy about any of these events,” Federline attorney Mark Vincent Kaplan said when he left a closed-door emergency hearing Friday afternoon. “There’s no winners here.”

Federline was not in court for the hearing, Kaplan said.

The attorney had said he did not expect the ruling to be released until Monday, but it was issued shortly after the hearing concluded.

The 26-year-old pop star remained hospitalized Friday.

Her latest troubles began about 8 p.m. Thursday when officers were called to her home to help resolve a dispute over her refusal to turn the children over to Federline, as dictated by their custody agreement.

It took two to three hours to resolve the conflict, said officer Ana Aguirre.

“There was a time where she was within the residence and wasn’t available to be speaking to the officers, apparently,” she said. “There was no threat to the children.”

“Police resolved the conflict,” Aguirre said. “Both children were turned over to her ex-husband Kevin Federline for custody, and she was in fact taken to a local hospital for medical treatment.”

Early police reports said officers thought Spears might have been under the influence of some substance, but Aguirre said there was no evidence of that.

“Our understanding is that was not the case,” she said.

Officers at the scene determined that paramedics “needed to be called” but it was unclear why, she said.

“We’re not aware of any type of injuries that she sustained” and she was not combative with authorities, Aguirre said.

Spears wasn’t arrested in connection with the custody dispute, Aguirre said.

Spears and Federline were married in October 2004 and divorced in July.
