Spears married dancer Kevin Federline last September in a surprise ceremony, and since that time there has been speculation about another addition to the family. The 23-year-old pop star made the announcement on her website on Tuesday.

"The time has finally come to share our wonderful news that we are expecting our first child together. There were reports that I was in the hospital this weekend. Kevin and I just want everyone to know that all is well. Thank you for your thoughts and prayers. Love Britney and Kevin," Spears wrote.
