The September 12 birth certificate, filed with Los Angeles officials this week, was the latest twist in the rumor and secrecy that marked the arrival of the once publicity-hungry pop star's second baby.
Not only was the birth at a Los Angeles hospital never officially announced by Spears or her husband Kevin Federline, but sources close to the couple led the world's media to believe that the boy had been named Sutton Pierce.
For weeks beforehand, the tabloid media was sure the former teen pop sensation was expecting a girl. Celebrity magazines had Spears stocking up on pink baby clothes and reported she planned to name the child Jamilyn after her younger sister Jamie and her mother Lynne.
But the official birth certificate records that Jayden James Federline was born September 12 at Cedars Sinai hospital in Los Angeles. Jayden, who at six weeks has yet to make his public picture debut, was born two days before the first birthday of Spears' first son, Sean Preston.
Spears, who put her phenomenal recording career on hold after marrying Federline in September 2004, announced her second pregnancy on a late night TV chat show and posed nude for Harper's Bazaar when she was six months pregnant.
