Simon Cowell discusses 'Idol Gives Back.'

5 of 7
American Idol has become a cultural phenomenon, but Simon says he never expected the show to take off like it has. "I genuinely thought after three weeks they'd take our show off and I'd be run out of the country," he says. "So every day we've been on ever since has been a bonus."

Since the show has been so successful, American Idol has decided to do something special in return for their good fortune. Fox, American Idol and the Charity Projects Entertainment Fund are teaming up to help fight poverty in the United States and Africa.

To kick off the effort, American Idol is airing a special two-night event called "Idol Gives Back" on April 24 and 25, 2007. After the competition ends on April 24, corporate sponsors will make a donation for every single vote cast that night. The star-studded results show on April 25 will rock the house with appearances from celebrities like Borat, Michael Bublé, Kelly Clarkson, Celine Dion, Il Divo, Josh Groban, Annie Lennox, Pink, Gwen Stefani and Carrie Underwood!
