Oprah Winfrey reportedly wants Rosie O’Donnell to keep her mouth shut after the former View co-host told Howard Stern that Winfrey and pal Gayle King “are the emotional equivalent of” a gay couple. “Oprah was so furious she had a warning message sent to Rosie,” a source tells the National Enquirer. “Oprah said if she were gay, she would say so.”
