Seventeen years after Kelly Clarkson won American Idol, she reunited with her judges.

She had Simon Cowell, Paula Abdul, and Randy Jackson on The Kelly Clarkson Show on Wednesday, and the four looked back at her audition and season of the competition series.

"I actually genuinely do not believe we would be sitting here today if you hadn't entered the show that year," Cowell told Clarkson. "The whole premise of this show was we had to find a star who was going to sell records."

The judges all agreed on the importance of her delivery of her winning song at the end. "It was a game-changer," Abdul said, with Jackson adding, "we looked at each other at the end at the finale and said, 'Wow. This thing is really going to work.' I think that was the moment that we knew."
