New York, Aug 21 : American talk show host Oprah Winfrey has told the editors of a magazine that she is tired of being on its cover every month.

Sources have revealed that the editors of O magazine have now been asked to find a substitute.

"Oprah has told the editors at O magazine she's tired of being on the cover every month," the New York Post quoted a source as saying.

"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," the source said.

However, the magazine's representative is sure that Winfrey will continue being the face on its cover.

"Oprah Winfrey has appeared on the cover of O . . . since its launch in 2000, and she will continue to do so," the rep stated.

"In fact, shoots for three upcoming covers will take place in early September," the rep added.

Meanwhile, the magazine's newsstand sales are down 17 percent from last year and circulation is down 1.7 percent.
