Simon Cowell Gives Big!
"It was so good, we're going to do it again," Simon says.
On this year's show, look for performances by current and former Idol contestants and winners. Celebrities like Bono, Brad Pitt and Miley Cyrus are scheduled to appear, too. "It'll be a big, big night," Simon says.
Simon says he's only just learned about the joy of giving. "I didn't realize that. It's taken me 48 years," he says. "It's going to catch on, this, because it is a very, very good feeling."
