Bono has been lined up to headline the second annual American Idol charity concert, set to air in the US on April 9th.
According to Variety, the U2 frontman will be joined by a host of stars for the Idol Gives Back show, which raises money for under-privileged children.
Black Eyed Peas singer Fergie is to take part, as well as Snoop Dogg, Annie Lennox and Mariah Carey.
Teen star Miley Cyrus - the face behind the hugely-successful Hannah Montana phenomenon - will also perform as will American Idol season four winner Carrie Underwood and ex-contestant Chris Daughtry.
And US network Fox has unveiled more of the star-studded lineup for the 2008 show, with actors Brad Pitt and Reese Witherspoon signed on to appear as well as NFL greats Peyton and Eli Manning.
While last year's show - which earned $76 million (£38.2 million) for charity - was split between the American Idol soundstage in Hollywood and the Disney Concert Hall, this year's event will move from the latter to the Kodak Theatre in Los Angeles, the regular venue for the Academy awards.
The inaugural Idol Gives Back show in 2007 was hosted by Ellen Degeneres and featured a glittering collection of A-list stars, including Gwyneth Paltrow; Hugh Grant; Keira Knightley; Dame Helen Mirren; Emily Blunt; Hugh Laurie; Matt Damon; Forest Whitaker; and former winner Kelly Clarkson.
