Magazine editors confirmed it was an outtake from their December 2013 cover story, praising the snap by writing, "It is real, it is honest, and it is gorgeous."
However, the photographer has taken issue with the unauthorised release of the image and now his lawyer has demanded anyone who published the picture online take it down.
In a cease and desist letter obtained by editors at website TMZ.com, the lawyer threatens to pursue legal action against anyone who refuses to remove the photo.
The notice also includes a statement from the photographer, confirming he took the image, which he insists was stolen and doctored.
