“American Idol” is getting a boost of star power for its season finale. Beyoncé, TLC, Lady Gaga, and Jennifer Lopez are among the artists reportedly set to appear on tonight’s big show.

Beyoncé will hit the “Idol” stage, dueting with the top 13 girls in a live musical number, according to The Hollywood Reporter.

Her fellow diva Lady Gaga will perform her Born This Way single “The Edge of Glory,” while there are reports that judges Jennifer Lopez and Steven Tyler will pair up for Aerosmith’s classic “Dream On.”

The surviving members of TLC, T-Boz and Chilli, are also rumored to perform at L.A.’s Nokia Theatre, but it is unknown what their involvement will entail.

Other names being thrown around are U2’s Bono and The Edge, Lil Jon, Tony Bennett (with top 3 contestant Haley Reinhart), and actor-musician Jack Black alongside Casey Abrams. Finalist Lauren Alaina will join previous “Idol” champ Carrie Underwood, while Scotty McCreery croons with country superstar Tim McGraw.

Tune in tonight at 8 p.m. on Fox to see all the surprises in store.
