A pair of very familiar Grammy winners are returning one last time to where it all began: American Idol.
Kelly Clarkson, who won the reality singing competition in 2002, and Carrie Underwood, who was crowned champion in 2005, will perform on Idol‘s series finale, Fox announced today.
The two-night finale, which airs April 6 from 8 p.m. to 9 p.m. ET/PT and April 7 from 8 p.m. to 10:06 p.m. ET/PT, airs live from the Dolby Theatre in Hollywood. It will be preceded on April 5 by American Idol: American Dream at 8 p.m. to 9:30 p.m. ET/PT, a retrospective that includes 15 seasons of memory-lane strolls from host Ryan Seacrest, current and former judges, former contestants, and Idol staffers.
Thursday’s big-send off will also feature group and solo performances by such former Idol contestants as Ruben Studdard, Fantasia, Taylor Hicks, Jordin Sparks, David Cook, Kris Allen, Lee DeWyze, Scotty McCreery, Candice Glover, Caleb Johnson, Nick Fradiani, Ace Young, Allison Iraheta, Amber Holcomb, Blake Lewis, Bo Bice, Brandon Rogers, Bucky Covington, Carly Smithson, Casey James, Chris Daughtry, Clark Beckham, Clay Aiken, Colton Dixon, Constantine Maroulis, Danny Gokey, Diana DeGarmo, Elliott Yamin, George Huff, James Durbin, Jessica Sanchez, Josh Gracin, Joshua Ledet, Justin Guarini, Katharine McPhee, Kellie Pickler, Kimberley Locke, Kree Harrison, LaToya London, Lauren Alaina, Melinda Doolittle, Pia Toscano, Sanjaya, Skylar Laine, and Tamyra Gray.
Kelly Clarkson —whose pregnancy required to pre-tape her performance for the finale — most recently returned to Idol as a judge a few weeks ago, and Underwood’s last appearance was in 2013.
