Britney Spears needs to be replaced by a body double for a nude Blender Magazine shoot because she is too “out of shape.”

The singer is baring all in a recreation of an iconic Marilyn Monroe photograph, but the magazine plans to swap her body with a more “in shape” model.

An advertisement placed in the magazine reads: “We are casting for a Britney Spears body double. You must have shoulder to medium length blonde hair. This person must also be in shape! 5’2″ to 5’5″. This will be a take off of a Bert Stern photograph of Marilyn Monroe in bed, from the last shoot before her death. Your face will not be shown in the final photograph/cover.”

The official word from a Blender rep: “We don’t comment on upcoming covers.”
