Kevin Federline arrived at Los Angeles Superior Court's Stanley Mosk Building Monday morning for the latest round in his ongoing custody fight with ex-wife Britney Spears. Shortly after 9 a.m. (the hearing was scheduled to begin at 9:30), Federline appeared, wearing a blue pinstripe suit and looking confident and upbeat. As the hearing time passed, Spears, 26, remained at home. A source said she had "no plans" to attend the session. Another source said she had been "strongly advised" by her legal team to attend the hearing, adding that the singer was told that "her attendance is important." The court gathering is expected to focus on Spears's four-hour Jan. 3 standoff with police, firefighters and paramedics at her Studio City home. Events that evening resulted with Spears being hospitalized at Cedars-Sinai Medical Center. Federline, 29, currently retains sole legal and physical custody of the couple's two sons, Preston, 2, and Jayden, 1. Spears was stripped of all visitation rights following her hospitalization. Also at issue Monday is whether the court will extend its ban on Spears's visitation. Federline's lawyer, Mark Vincent Kaplan, says it's possible Spears might not see her children until April, when the ex-couple's custody trial begins. (Federline has requested primary physical custody.) Over the weekend, Spears continued to be seen with paparazzo Adnan Ghalib, 35. Among their stops were a Mercedes dealership and a department store, where Spears reportedly shouted a profanity at a bystander who attempted to take her photo.
