Britney Spears and ex-husband Kevin Federline have agreed on a custody arrangement for their two sons, probably averting a family court trial set for next month, an attorney for Federline said Friday.

A court spokesman confirmed that a resolution of the long custody case was in the works but that Superior Court Commissioner Scott Gordon has not signed off on it.

"We have reason to believe there will be imminent developments" resolving the issues, spokesman Allan Parachini said.

After a closed-door meeting with the pop star's attorney and the judge today, Federline's attorney, Mark Vincent Kaplan, declined to discuss terms of the deal, but said it would be finalized by the court "in the very near future." Kaplan told OK magazine the deal gave Federline full legal and physical custody of the toddlers while continuing visitation rights for Spears.

Spears and Federline did not attend the hearing.

Federline gained custody of Sean Preston and Jayden James in October after Spears exhibited erratic behavior. She was hospitalized for psychiatric problems in January.

The performer is allowed monitored visitation with her sons. Her attorney, Laura Wasser, said Friday that Spears was "doing well."

"She has her kids today and she has them overnight," she said as she left court.
