American Idol‘s All-Star Duets and solo rounds will hit the air on April 4, and Billboard has an exclusive first peek at the A-list lineup of special guests who will join the singers vying to make the live rounds.
The top 24 singers will face off in the all-star round in a bid to make it to the live shows, where the top 16 will start competing on April 11.
The contestants will try to wow the judges by performing duets with surprise celebrity guests including: Idol season five runner-up Katharine McPhee, Jason Aldean, Tori Kelly, Ben Rector, Jimmie Allen, Joss Stone, Brian McKnight, Jewel, Incubus singer Brandon Boyd, Maroon 5’s PJ Morton, Josh Groban and Ryan Tedder.
Each celeb will be paired with two contestants and sing with each separately after the top 24 are revealed on tonight’s (March 29) show. Idol‘s “411 (All Star Duets and Solos)” will air on April 4 (8:00-10:00 p.m. ET) and April 5 (8:00-10:00 p.m. ET) on ABC. But first, Monday night (March 29) will feature the second evening of showstopper performances for the remaining contestants vying for the top 24.
Sunday night’s intense battles saw Alyssa Wray blowing the judges away with her powerful rendition of “I’m Here” from The Color Purple as well as some serious vocal fireworks from Jason Warrior, a rough run for judge’s favorite Murphy and a cliffhanger showdown between the show’s young divas, Casey Bishop and Alanis Sophia.
