LOS ANGELES -- Britney Spears arrived in court giggling Friday but later was heard swearing during a break in a closed hearing that ended with no decision on her bid for shared custody of her two young sons with Kevin Federline. Lawyer Mark Vincent Kaplan said the court was expected to issue a written ruling by Tuesday. Spears did not comment after the hearing. Earlier, she uttered an epithet when a reporter asked how the proceedings were going. Attorney Sorrell Trope, who represents Spears, said "something has changed, but I can't say what."
