It’s so hard to say goodbye, but at least Oprah Winfrey is going out with a bang.

Considering the number of A-list guests featured in the final taping, we have to wonder who wasn’t at the United Center in Chicago to salute the mogul who revolutionized TV for 25 years. The stadium was packed to the brim with fans and stars who all came to salute Oprah (and brought her to tears on a few occasions).

Of course Oprah’s man, Stedman Graham, and her bestie Gayle King were in the house to cheer her on. And there were also plenty of dedication performances. O’s mentor, Maya Angelou, did an original poem to honor her, while Alicia Keys hit the piano to dedicate her song “Superwoman” to O. Stevie Wonder made Oprah smile by singing his classic hit “Isn’t She Lovely” and Aretha Franklin sang a touching rendition of “Amazing Grace.” Beyoncé gave a booty moving performance of her new song “Run the World (Girls).”

Other celeb friends, including Patti LaBelle, Will and Jada Pinkett Smith, Tyler Perry, Queen Latifah, Michael Jordan, Jay-Z, Usher, Halle Berry, Jamie Foxx and Madonna stopped by. Even in the wake of her husband Arnold’s scandal, Maria Shriver turned up looking fabulous and gave Oprah hugs and love (insiders say the two made jabs at the “Governator." Yikes).

Actor Tom Hanks said, "Today, Oprah Winfrey, you are surrounded by nothing but love! Your studio just wasn't big enough to hold it all, so here we are."

This episode will air May 25.
