'American Idol' Finale Reportedly To Feature Lady Gaga, Beyonce Performance

Carrie Underwood, Steven Tyler, Jennifer Lopez also rumored to be taking the stage.

As "American Idol" fans sweat out the final hours before they find out whether Scotty McCreery or Lauren Alaina will be crowned the new people's champ, more details have emerged about who will perform on the season 10 finale on Wednesday night (May 25).

As always, producers have kept a tight lid on what surprises are in store for the two-hour finale — and a spokesperson for "Idol" did not return requests for comment at press time. But according to The Hollywood Reporter, a pair of this year's mentors will be back to celebrate the coronation.

Citing unnamed production sources, the trade magazine reported that in addition to U2's Bono and The Edge performing with castmembers from the troubled Broadway musical "Spider-Man: Turn Off the Dark," [artist id="1236911"]Beyoncé[/artist] and [artist id="3061469"]Lady Gaga[/artist] will take the stage.

The story claimed that both pop divas, who helped mentor this year's finalists, will team up with all-time "Idol" champ Carrie Underwood to perform a group medley with judge Steven Tyler and title contenders McCreery and Alaina. There is also unconfirmed talk that fellow judge Jennifer Lopez will also take the stage for a command performance.

In addition, bearded season 10 growler Casey Abrams will take the stage with "Kung Fu Panda 2" funnyman Jack Black.
