Oprah Winfrey has expressed her desire to host the final episode of her TV show in a huge open-air football stadium in Chicago.

The mogul is planning a star-studded finale next September (11) when the Oprah Winfrey Show will end its 25-year run on U.S. TV.

And the talk show queen has hinted she wants to move the production from her Chicago, Illinois studio to the city's 61,500 capacity Solder Field- the home of the Chicago Bears football team- in a bid to pack in a bigger audience.

But Winfrey has admitted the notoriously unpredictable climate in Chicago could scupper plans for an open-air finale.

"I don't know if that's going to happen. You can never count on Chicago weather," the Daily Express quoted her as telling TV Guide.

The star is stepping down from her syndicated talk show to run the Oprah Winfrey Network. (ANI)
