Ryan had revealed on his radio show that the 'Hit Me Baby One More Time' hitmaker is pregnant.
He further insisted that the pregnancy report is authentic, as the information comes from a 'reliable source'.
However, Britney's manager Adam Leber has dismissed the reports and has insisted that Ryan should have checked up with him before circulating such a vague piece of information.
"She's absolutely not pregnant. I have no idea where this ridiculous rumour came from. Ryan has communication with our camp and could have checked this before saying it," Contactmusic quoted Leber, as telling PerezHilton.com. (ANI)
