Ever since her [article id="1580689"]hospitalizations[/article] earlier in the year and a judge's order giving her dad, Jamie, [article id="1580840"]control over her finances and estate[/article],

Britney Spears has mostly been on her best behavior. That change from her former [article id="1574106"]partying, car-accident-prone persona[/article] might have played a role in a judge's decision on Tuesday (June 24) ordering a change in the singer's visitation agreement with her two young sons, Sean Preston and Jayden James.

According to People magazine, Superior Court spokesman Allan Parachini confirmed that a change in the terms of the agreement had been ironed out during the closed-door court hearing attended by Spears and ex-husband Kevin Federline. The terms of the new arrangement were not announced, but Parachini said Spears' parenting coach, Lisa Hacker, answered questions from the court and the hearing went well for the singer.

"There was a change in [Spears's] visitation status that was ordered," Parachini said. "Britney's demeanor in court was businesslike. I think any judge is pleased to see progress being made by parties in a case." While People was vague on the changes, citing unnamed sources, TMZ.com reported that the commissioner in the case had awarded Spears overnight visitation with her sons.

Another hearing on the matter was set for July 15.

In May, Spears attended a hearing on the custody matter after which Federline's attorney, Mark Vincent Kaplan announced that

and Federline has had sole legal and physical custody of the couple's sons since January 3, the night [article id="1578990"]Spears was hospitalized[/article] after refusing to give the children over to his representative.

Since then, she has had restricted, monitored visits with the children.
