Last night, American Idol and the Charity Projects Entertainment Fund made history when the Top 6 finalists sang their hearts out and viewers helped change the lives of the less fortunate here in America and in Africa when each of their millions of votes netted a charitable donation. Find out tonight live, during this star-studded evening, who will sing again next week and who will go home. World-renowned artists and celebrities scheduled to appear include Kelly Clarkson, Hugh Grant, Keira Knightley, Forest Whitaker, Gwen Stefani, Josh Groban, Michael Bublé, Annie Lennox and Sacha Baron Cohen (Borat), among many others. In addition, America will have an opportunity to make their own donations.
