Britney Spears has denied rumours she is pregnant after Ryan Seacrest claimed she was.
The 'American Idol' host told listeners on his Los Angeles radio show he had been told by a "reliable source" that the singer was expecting her third child.
The Press Association quotes Britney's spokesman as saying: "She's absolutely not pregnant, I have no idea where this ridiculous rumour has come from."
The 27-year-old singer - who is mother to sons Sean Preston and Jayden James from her marriage to ex-husband Kevin Federline - is currently on her world Circus tour.
Spears recently added a dozen new dates to the European leg of her tour including shows in Dublin, Paris, Berlin, Stockholm and Moscow.
