Spears waits for baby number two

Britney Spears' husband Kevin Federline has laughed off reports his famous wife is pregnant with their second child.

The couple, who wed in September 2004, welcomed Sean Preston into the world last September. Federline has two children Kori and Kaleb from a previous relationship with actress Shar Jackson.

Earlier this month, reports claimed the Toxic singer had announced her second pregnancy at Malibu, California store Shabby Chic, declaring: "That's right, number two," while rubbing her rounded belly.

However, backstage at the Grammy Awards on Wednesday, Federline said, "It would be a few years (before I'm a father again)."
