In a clip released on EllenTV.com, Ellen revealed that Oprah herself shared the news with her fellow talk show host on Thursday afternoon.
"Right before I came out here, I got a call from Oprah and she told me that she is announcing that next year will be her last year," Ellen revealed to her audience on Thursday, following a taping of her show. "It will be her 25th year and she feels like it's time for her to stop."
Ellen credited Oprah for opening up the market and allowing talk show hosts like herself to make it.
"I don't think I could be here without her. I think she has blazed a trail," Ellen said. "She is an amazing woman. She will always be the Queen of daytime television and she also said she is leaving me all of her money. I was like, thanks Oprah, thank you."
Ellen said she has fond memories of her recent O Magazine cover shoot with Oprah and she can't wait to see what happens with Lady O in the future.
"She is an amazing woman. I love her and we've gotten very close over this ridiculous idea that I had of getting on the cover of O — a silly dream… And now we talk all the time and she is fantastic and I love her and I wish her the best," Ellen told her audience. "She deserves to rest. She has worked really, really hard."
