Ex-talk show host Rosie O'Donnell — who turned McCall's into Rosie in April 2000 — has quit the magazine. Its last issue comes out in December. Blaming publisher Gruner + Jahr for gradually usurping her editorial control, she told reporters: "I cannot have my name on a magazine if I cannot be assured that it will represent my vision and ideas." While neither side is suing yet, Gruner sure sounded litigious in a recent memo to its employees: "It is truly shocking and disappointing that Rosie would walk away from her obligations... In doing so, she destroys the value of the business we created and violates the conditions of our binding contract... Rosie cannot simply ignore that obligation." (Them's fightin' words!)
