'American Idol' mystery solved: David Archuleta, Rihanna to perform
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.
