AceShowbiz - %cDavid Archuleta% and %cJason Derulo% have been added to the line-up of this coming Wednesday's result show of "American Idol". The two are going to join previously-announced performer %cRihanna% at the upcoming episode of the reality singing competition.
In honor of this week's %cJohn Lennon% / %cPaul McCartney% theme, David is booked to once again cover John's worldwide hit "Imagine". The 19-year-old singer first showcased his rendition of "Imagine" during the show's season 7. The performance had gained him praise from %cSimon Cowell%, %cPaula Abdul% and %cRandy Jackson% as "the one to beat" although he finally lost the winner title to his pal %cDavid Cook%.
While David Archuleta is set to reprise his 2008 performance, Jason Derulo and Rihanna are scheduled to deliver their own songs. Jason who cited judge %cKara DioGuardi% as one of his mentors will sing "In My Head" and the Barbadian singer will entertain audience with "Te Amo".
