Spears took three bathroom breaks during the hearing, with her mood souring as the day wore on. At an early break, she told reporters, "Everything's great," but at a later break she cursed at a reporter asking how she was, saying, "Snort it, f--- it."
Federline's attorney, Mark Vincent Kaplan, was asked after the hearing if it was contentious. "When I'm there, it's always contentious," he quipped.
The session ended with Superior Court Commissioner Scott Gordon making no ruling.
"There was testimony and argument during the hearing," says court rep Meredith Pierce, "but Commissioner Gordon did not make a ruling today. He took the case under submission, meaning he'll consider both sides and will craft a new court order."
Spears's attorney, Sorrell Trope, said he was "absolutely satisfied" with the court session, and noted that Spears would continue to have overnight visitations with her sons.
"I left with a favorable feeling," he said.
The next hearing is Nov. 26.
Media FrenzyThe singer and her ex-husband both arrived at the courthouse amid a media frenzy earlier in the afternoon.
Spears, who drove up in her white Mercedes-Benz along with longtime friend Alli Sims, wore a long-sleeved dress and sunglasses. Spears, who came through security at around 1:40 p.m., followed by most of her legal team, smiled slightly and ignored questions as she walked into the courtroom.
Five minutes later, Federline arrived decked out in a dapper gray suit and sporting close-cropped hair and diamond studs in each ear. He silently made his way into the courtroom with his attorney.
Inside the courtroom, Federline took a seat and discreetly glanced over to his right where Spears was seated. She, however, kept her arms folded in front of her, and never turned to look at her ex.
After the judge entered the courtroom, both Spears and Federline stood simultaneously and were sworn in. When asked to state her name, Spears replied quietly, "Britney." Federline stated his full name.
Reporters then had to leave the hearing.
The Ongoing BattleFor now, Federline retains physical custody of sons Preston, 2, and Jayden James, 1. Spears has monitored visitation rights, and one overnight per week with her children.
The judge is not expected to reinstate the 50-50 custody arrangement that was in place before Spears was stripped of custody and allowed only visitation.
