He will perform two songs from his new Christian album, "Alone with My Faith", which he recorded during lockdown, while Daigle will sing her 2019 hit "Look Up Child".
"It's really nice to be back," he says. "I had such a good time when I was a judge, and before that, a mentor. So any chance I get to see those folks again, I welcome. I have a lot of friends there."
Daigle adds, "I'm excited to be back with people that I so enjoy. We did rehearsals and the Idol team, like the band, is insane. We had a ball. The band nailed it... It's also really refreshing how kind they are."
Daigle auditioned for the show in 2010 and 2012 when she just missed out on making it to the top 10.
"I don't have any disdain or any negativity toward the show," she explains. "At the time I was so young and naive and I don't think I knew who I was yet. So I could have been pulled in so many different directions artistically. I feel like it gave me an opportunity to step back... I'm actually really excited that it worked out this way."
