TMZ solved the mystery of Britney Spears' and KFed's second child. There were rumors that it was a girl, but it's a boy. Unfortunately, the name of the birth certificate, filed today, is Jayden James Federline NOT Sutton Pierce Federline. KFed signed the thing himself on September 13th. He can't read too good, so SPF probably read him the details.
So there you go! Jayden James Federline it is! Click here to see the certificate, like you care.
