It's official: Jayden James Federline

A birth certificate for the second child of Britney Spears and Kevin Federline was filed today at the office of the LA County Registrar, finally providing proof of the name and sex of the baby. Uncovered by TMZ, the birth certificate lists baby boy Federline's name as Jayden James Federline and was signed by KFed the day after his birth. The child's name had been previously reported as Sutton Pierce Federline, and there was even recent controversy as to whether the couple's new baby was a boy or a girl.
