Talk show queen Oprah Winfrey just filmed the epic star-studded last episodes of The Oprah Winfrey Show after 25 seasons since the first episode on September 8, 1986. Oprah’s big finale airs on Wednesday (May 25), but we have some exclusive details of the special guests, performances and apotheosis.

According to Bumpshack’s source, the Oprah finale, which was filmed at the United Center in Chicago, Illinois last week, is actually divided into two episodes hosted by the one and only Tom Hanks. Actor Tom Cruise led the pack of many special celebrity guests basically just praising Oprah’s work for the past 25 years.

Patti LaBelle and Josh Groban sang a duet of the song “Somewhere Over The Rainbow”, the classic ballad from “The Wizard Of Oz” sung by Judy Garland. This musical moment was followed by Madonna’s appearance. The Queen Of Pop talked about the importance of Oprah’s work with the girls’ school (Oprah Winfrey Leadership Academy for Girls) in South Africa.

Beyonce took over the stage to perform her latest hit “Run The World (Girls)” – and she had to perform it TWICE due to technical difficulties. Other special guests, Katie Holmes, Halle Berry and Queen Latifah, also came to say just how fabulous they think Oprah really is. This must have been quite an ego trip for Oprah.

Comedian Jerry Seinfeld also entertained the audience with a stand-up segment. Rascal Flatts closed the first episode of the big finale with a special performance and, of course, Oprah got emotional. Tom Hanks was joined by co-hosts, Will Smith and Jada Pinkett Smith, for the second part of Oprah’s big finale.

Jada called Oprah a “mother to millions” for all she has done for people during all these years, which was followed by testimonies of girls sharing their stories and explaining how Oprah “saved” them. Very melodramatic.

Next was Jamie Foxx who started talking nonsense about “how he wanted to bend Oprah over and was surprised Steadman hasn’t “kicked his ass” because of their attraction.” No kidding! Jamie started to sing “Isn’t She Lovely” as Stevie Wonder joins the party.

Stevie also sang a new song he has been working on and dedicated it to the talk show queen. Simon Cowell continued with a speech about how “honest” he and O always were with each other. Romance? Attraction? And now honesty? Creepy, weird and inappropriate – all in the name of entertainment!

Rosie O’Donnell surprised the audience and Oprah with a Broadway-esque performance. Maria Shriver, whose estranged husband Arnold Schwarzenegger just publicly admitted to have had a love child more than a decade ago, and Gayle King joined Oprah for more images of how the show changed the life of many people.

Oprah’s favorite author/poet, Maya Angelou, read a poem while singer Alicia Keys played the piano. Oprah cries! Alicia sang “Superwoman” before Aretha Franklin performed a gospel version of her song “Amazing Grace” and Usher finally closed the show with a rendition of “Oh Happy Day”.

This is it! RIP Oprah Winfrey Show.
