'American Idol': Kelly Clarkson and Fantasia Barrino to duet on Season 9 finale

kelly-clarkson-getty.jpgWith just hours until the Season 9 winner of "American Idol" is announced, we still don't know all the details about who will be performing in tonight's (May 26) finale.

Before we find out whether Lee DeWyze or Crystal Bowersox will get the title, we'll have the chance to revisit some past winners when Season 1's Kelly Clarkson takes the stage with the Season 3 winner, Fantasia Barrino.

Their duet is particularly special because it's dedicated to our favorite cantankerous judge. Clarkson's Facebook page announces, "Don't miss Kelly performing tonight on American Idol! She and fellow winner Fantasia will be performing 'Together We Are One' as a farewell performance to Simon Cowell."

Cowell has said that Barrino's Season 3 performance of "Summertime" is his all-time favorite "Idol" moment.

Traditionally, the finalists perform with established artists - last season, Adam Lambert performed with Queen and Kris Allen performed with Keith Urban. This season, Christina Aguilera will perform, and rumor has it that Chicago may be one of the special guest acts.
