Oprah May Save the Biggest Star in the World for Her Final Guest

She's done it all, my source says, and "only one person could do that and that is Oprah herself."

Oprah has spoken before of her love of the final episode of 'The Mary Tyler Moore Show,' where Mary turned out the lights and left. Is she planning something in that vein? Perhaps, especially since the third and second to last shows (May 23-24) are going to be star-studded affairs in what producers have dubbed "Surprise Oprah! A Farewell Spectacular."

The free shows, being held at Chicago's United Center on May 17, will include "some of the biggest names in movies, music and television in a one-time-only gathering to celebrate the 25-year legacy [of the show]."

Best of all, viewers will be treated to something they rarely see: a surprised Oprah.

"As most of our viewers know, being surprised is not one of Oprah's favorite things," said Harpo executive producer Sheri Salata. "In the spirit of our farewell season, she is making a rare exception and we intend to make the most of that opportunity. It will be something to see!"

Since those episodes will clearly be chocked full of stars, glitz, balloons and freaked-out audience members, show insiders tell me that Oprah may want to go out for good in a more understated, introspective way.

"Her last show will look back at some of her most important and favorite moments from her show," a source says, not surprisingly. "But at the end of the day the show will end where it started. A woman with a microphone looking into a camera and trying to make the world a better place."
