Kelly Clarkson and Oprah

4 of 11
Just three years ago, Kelly Clarkson was a small-town girl, working as a cocktail waitress in Texas. Now, she's a triple-platinum musical sensation thanks to a little show called American Idol.

Kelly won the first season of Idol with the song "A Moment Like This," but her moment didn't stop there. She went on to receive a Grammy nomination, two MTV Video Music Awards and four top 10 hits. Her smash single "Breakaway" just broke Celine Dion's record for most weeks at number one!

She also holds the distinction of being the only American Idol contestant to never feel judge Simon Cowell's wrath.

"So a while back I talked to Simon and he says he knew from day one that you would win," Oprah says. "He said he always knew it."
