Preliminary plans were revealed today for two of the final episodes of “The Oprah Winfrey Show,” Entertainment Weekly reported. The second-to-last and third-to-last shows will tape May 17 at United Center in Chicago for broadcast May 23 and 24.

The shows will geature “the biggest names in movie, music and TV,” according to an announcement by Harpo Productions. But just who those names are is being kept secret–even from Winfrey. The daytime talk queen is infamously uncomfortable with surprises, but she agreed to let the show’s producers surprise her just this once.

Said exec producer Sheri Salata, in a statement: “As most of our viewers know, being surprised is not one of Oprah’s favorite things. In the spirit of our farewell season, she is making a rare exception and we intend to make the most of the opportunity.”

The taping, dubbed “Surprise Oprah! A Farewell Spectacular,” has reportedly been in the works for weeks.
