Pop star Britney Spears has slammed reports she is pregnant with her third child. The TOXIC star's manager, LARRY RUDOLPH, rubbishes the reports telling American publication Us Weekly that "Britney is not pregnant," calling a recent tabloid report claiming that Spears is expecting "absurd." Two months after splitting from husband KEVIN FEDERLINE, the singer, 25, has moved on and is dating actor/model ISAAC COHEN. Rudolph believes that the "ridiculous" report came from an incident last week (ends14JAN07), in which Cohen accidentally wiped peanut butter on his shirt while he was with Spears. Observers had wrongly concluded that she had vomited and assumed because she was vomiting, she must be experiencing morning sickness. He adds, "Because Isaac didn't lick the peanut butter off his fingers, someone decided that it must not be peanut butter, but must instead be Britney's vomit. Ridiculous!"
