"American Idol" is about to get a double dose of star power: Kanye West and Kelly Clarkson.
The Grammy winners will share the stage as performers during Wednesday's elimination show.
West, making his first appearance on the top-rated Fox series, will perform his hit song "Heartless" from his latest album "808s & Heartbreak."
Clarkson, the original "American Idol," will sing her chart-topper "My Life Would Suck Without You," off her new album that drops Tuesday.
The show _ a ratings juggernaut since it debuted in 2002 _ has attracted numerous top artists as mentors and performers in recent seasons. Among them: Mariah Carey, Prince, Gwen Stefani, Dolly Parton and Jennifer Lopez.
