It's official: Britney Spears has given birth to her second child and he is a boy. Kevin Federline, Britney's husband, confirmed the news yesterday but he refused to reveal the baby's name. And, because the birth in itself was such a huge event, some celebrity magazines have done their homework and discovered what the baby's name is going to be.

'People' Magazine states for a fact that the second Spears-Federline infant will be named Sutton Pierce Federline, so that his initials be the same as those of his brother's, Sean Preston Federline. The reporter who made the claim says he got the information from a very reliable source who, nonetheless, asked to keep his/her anonymity.

It seems that Britney and Kevin chose the SPF name to mark the fact that the second boy was born only within hours of Sean Preston's first birthday and within days of their wedding anniversary. And the rumor that the pop singer launched herself that she will be having a girl, whom they will call Jailynn, was just a clever maneuver to send the paparazzi off track.

Until this moment, nobody from the Spears-Federline camp was willing to openly tell the baby's name, other than the source, or sources, cited by the magazine. But media reports state that a public announcement will be made in the following days, as soon as the pop star will check out of the private clinic were she gave birth.
