Britney Spears not Pregnant, Just Fat!

Britney Spears' manager, Larry Rudolph, tells Us Weekly that "Britney is not pregnant," calling a recent tabloid report claiming that Spears is expecting "absurd."

On Wednesday, In Touch Weekly reported that Britney Spears's friends believe that the 'Toxic' singer may be pregnant again.

"I've seen her during the last two pregnancies and she has the same look now," a "pal who sees Britney every week" told the mag. "She's heavier, but that's not it. It's the sparkle in her eye. She always gets that sparkle when she's pregnant, like she's relaxed and happy."

The friends' also point to Spears still being fat, drinking water and her getting sick lately

"Her dancers were indulging in Malibu rum and pineapple drinks and taking shots of vodka," a witness to a January 14 party at a Las Vegas casino told the mag. "But Britney drank bottled water."

Spears gave birth to her second child only four months ago.

Rudolph tells Us that he believes that the "ridiculous" report came from an incident last week in which Spears' new boyfriend, Isaac Cohen, accidentally wiped peanut butter on his t-shirt while in the company of Spears.

"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," Rudolph joked. "Ridiculous."

A source tells Us that Spears spent last night working on her upcoming album with Pharrell in an L.A. recording studio.
