Posted October 26, 200618 yr TMZ Solves Baby Mystery, It’s Jayden James Federline TMZ has obtained a copy of the birth certificate for the latest addition to the Spears/Federline family, and now it’s official — it’s a boy! The certificate, filed today at the L.A. County Registrar-Recorder’s office, reveals that the boy’s name is Jayden James Federline. The certificate is signed by K-Fed himself, although a close inspection reveals that the signature is more like printing. Daddy Fed inked his name on Sept. 13, one day after Jayden was born. There was considerable confusion surrounding the birth of Britney’s second child. Originally the baby’s name was reported as Sutton Pierce Federline. Recent reports also indicated the baby was a girl. You can take a look at the birth certificate exclusively on TMZ (PDF).
