LOS ANGELES, California (AP) -- Troubled pop star Britney Spears has finally given testimony in her custody dispute with ex-husband K-Fed over their two boys, according to published reports.
Paparazzi swarm Britney Spears on January 14 outside a Los Angeles courthouse.
People.com and TMZ.com report Spears was seen leaving the Los Angeles-area office of Kevin Federline's lawyer about two hours after she arrived Monday.
Spears has been having trouble making recent legal dates.
On December 12, she called in sick for a court-ordered deposition, then arrived late at the lawyer's office on its rescheduled date, January 3.
That night she was taken to a hospital after a stand-off in her home when she refused to return the children to Federline's bodyguard following a visit.

Spears' next court hearing is scheduled for February 19th, when she'll try to regain a judge's permission for visits with her two young boys.
Spears married Federline in 2004 and filed for divorce in 2006.
Throughout 2007, her behavior was erratic -- and highly public, as a train of photographers trailed her everywhere.
A court ordered her to undergo random drug and alcohol testing, and to temporarily give the boys to Federline.
