david archie imagine 'American Idol' mystery solved: David Archuleta, Rihanna to performWhen a few hints were dropped by an “American Idol” insider earlier today, Zap2it‘s “Idol” fans investigated who the “mystery performer” would be on the Wednesday (April 7) results show. Now, the official American Idol site has confirmed that David Archuleta will appear.

Archie’s rendition of John Lennon’s “Imagine” secured his position as a top contender during Season 7, so we’re looking forward to him reprising his performance in honor of the Lennon/McCartney themed week.

Two weeks ago, Archie’s friend and competitor David Cook took the stage to show the current idols how to rock a Rolling Stones song. We’re sure Archie has a few things to teach the current Top 9 contestants, too.

In addition to Archuleta, Rihanna will perform her latest single “Te Amo.” Jason Derulo will sing “In My Head” off his self-titled debut album.
