Britney's Second Kid Visit

Britney Spears has seen her sons again.

Two-year-old Preston and one-year-old Jayden were driven to her Studio House by Kevin Federline's bodyguard for a three-hour visit.

It was the second visitation in three days.

On Saturday, Britney saw her children for the first time since January 3 after working out a structured visitation arrangement with K-Fed.

Meanwhile, lawyers for her father Jamie filed another round of papers in federal court on Monday.

He was urging a judge to quickly end a civil rights challenge to Jamie's control of his daughter's $100 million estate and keep the co-conservatorship case in state court.
