The latest AI champ will return to the the singing reality show’s stage for the first time since being crowned the Season 7 winner, and I’m sure it’s gonna be a blast! And no, this is not an April Fools Day joke considering that David Cook will perform on that day. But then, you never know with those American Idol producers! Especially since they haven’t yet announced what the top 9 finalists will perform this week

Anyway, David Cook will sing “Come Back to Me,” the latest single off of his self-titled debut album. His guesting comes in the midst of his first headline tour, which kicked off February 13 and has played to sold-out venues. Performing on American Idol that same night is Lady Gaga, singing “Poker Face.” Lady Gaga’s debut album, The Fame, was released in 2008, and its first single, “Just Dance,” netted a Grammy nod for Best Dance Recording. No, David Cook and Lady Gaga won’t duet :-p
