Baby Boom

"It's a boy!" Britney's website announced following the birth of son Sean Preston in September 2005. The pregnancy was not a surprise to the 23-year-old pop star, who had been very open about her desire to start a family with Federline. Shortly after their wedding, MTV quoted one of Britney's online posts: "A lot of people think you should wait till you're older to have kids. I've had a career since I was 16, have traveled around the world and back… The only thing I haven't done is experience the closest thing to God, and that's having a baby. I can't wait!"
