Report: Britney Spears is pregnant again

Britney Spears is pregnant with her second child with husband Kevin Federline, the Web site of Us Weekly is reporting,

According to the Us weblog, Spears was spotted at the swimming pool of the Caesar's Palace casino in Las Vegas over the weekend and was visibly pregnant. Sources then confirmed the pregnancy to the magazine.

The report is not the first time speculation has surfaced about Spears having a second child on the way. MSNBC.com's Jeannette Walls reported in February that the pop star was rushed to the hospital with early signs of pregnancy.

Spears' rep denied it at the time. But her camp has been silent since the Us report surfaced Tuesday night.

Spears, 24, and Federline, 28, have been married since September 2004. Their first child, son Sean, is seven months old.

Federline has two children from his previous relationship to Shar Jackson.
