For the second time in three years, "American Idol" contestants are taking on the works of John Lennon and Paul McCartney. This time, they're doing it with a little help from their friends.

Fox announced Monday (April 5) that this week's results program, airing Wednesday at 9 p.m. ET, will feature performances by Rihanna, singing "Te Amo"; Jason Derülo, singing "In My Head"; and season-seven runner-up David Archuleta, performing Lennon's "Imagine."

While this is the first appearance on the wildly popular show for Rihanna and Derülo, 19-year-old Archuleta is of course most widely known for his run on the program, making his mark during season seven with his showcase performance of the erstwhile Beatle's famous solo hit.

The song, in fact, became a calling card of sorts for the then-17-year-old crooner, who first performed it in only his second week on the show. At the time, his rendition of the tune [article id="1582392"]catapulted him to front-runner status[/article], leaving then-judge Paula Abdul teary-eyed and igniting a wellspring of support. Archuleta made it all the way to the final show, failing only to beat rival David Cook.

Rihanna, Derülo and Archuleta are the latest high-profile singers to be featured on "Idol" this year, following performances from [article id="1635229"]Diddy-Dirty Money[/article] and [article id="1635228"]Usher[/article] last week and [article id="1634657"]Miley Cyrus, Demi Lovato and Joe Jonas[/article] the week before.

Songs from the Lennon/McCartney playbook were originally featured in the first two weeks of the season-seven finals.
