The End of an Era: Oprah's Final Show

With just one week to go before her final show, the city of Chicago is pulling out all the stops to accommodate the Queen of Talk!

20,000 Oprah fans will pack the stands tonight at the United Center in downtown Chicago for the taping of two star-studded farewell shows. It's the home of the Chicago Bulls and the team was scheduled to have a playoff game tonight, but the game was moved up to Sunday just to accommodate Oprah!

Oprah's producers are staying tight-lipped about the guest list for the extravaganza because the details are all a surprise for Oprah, but they're promising celebrities from film, television, and music.

Fans can expect some of Oprah's most popular guests, like John Travolta, Will Smith, Mariah Carey, and Tom Cruise.

And there's also speculation that Maria Shriver will appear on Oprah's final show on May 25th. It will be her first TV interview since the stunning announcement that Arnold Schwarzenegger fathered a love child.

Kirstie Alley, who famously appeared on Oprah wearing a bikini, hinted to us backstage at Dancing with the Stars that she might even make a surprise appearance.

"I know that whatever she's done so far, she will surpass with what she does in the future," said Alley.
