Sean Preston, Jayden James Federline: Just Rollin' With it

While mom's away, Sean Preston and Jayden James Federline will play... and be pushed around in little toy cars by a random nanny person. See below.

On their first day under custody of father Kevin Federline, young Sean Preston (2) and Jayden James (1) motored around outside Federline's home in Tarzana, Calif.

During the short ride, Sean Preston and Jayden James fussed at times but cheered up when their nanny picked a flower for them to play with. They cry and whine less than their estranged mother, the frequently drunk Britney Spears.

Spears was stripped of custody last week, but will be allowed closely monitored, supervised visitation rights as of yesterday, a judge ordered.

The arrangement was decided at a three-hour closed-door session attended by Federline, who was wearing an eye patch because, his lawyer says, "His eye was sore." No further explanation was given. Britney Spears did not attend.
