One source said, "Oprah has told the editors at O magazine she's tired of being on the cover every month. It's a pain. It takes a lot of time and energy and she's sick of it. She's given them six months to figure out what to do without her." Meanwhile, the magazine's newsstand sales are down 17 percent from last year and circulation is down 1.7 percent. A rep for the monthly said, "Oprah Winfrey has appeared on the cover of O . . . since its launch in 2000, and she will continue to do so. In fact, shoots for three upcoming covers will take place in early September."
