Today, outside of her iconic music career, many may know Kelly Clarkson as the daytime talk show host who covers hits such as Billie Eilish's "Happier Than Ever" with her signature powerhouse vocals, or perhaps as one of the judges from The Voice.

But Clarkson's Hollywood Walk of Fame ceremony reminded everyone of her roots this week: American Idol.

Clarkson was the winner of the inaugural Idol season 20 years ago in 2002.

Back then, the show was co-hosted by Ryan Seacrest and Brian Dunkleman. Long before Katy Perry, Luke Bryan and Lionel Richie took their places on the judges' panel, Randy Jackson, Simon Cowell and Paula Abdul were the show's iconic trio of judges.

So it was only right that they reunited for Clarkson's Walk of Fame star unveiling, which took place Monday (Sept. 19).

According to People, Abdul even changed her flight so she could be there for the special day.

"I'm so proud to be here, honored. I changed my flight just so I could be here. I wouldn't miss it for the world. Kelly — not only the trajectory of your life has changed, but you helped change the trajectory of everyone's lives," Abdul said during the ceremony.

Abdul also talked about how she would "corner" Clarkson on set and ask about her singing background.

"I'm the one that would force myself to talk to her and corner her in the elevator. 'Where did you get your training from? You're an opera singer, I can tell,'" she said.

The sweet speech also included a note from Abdul about how Clarkson made her "believe like a kid believes in Santa Claus. That young, talented people can make it — and they can make it big time."

On Instagram, Clarkson recently reflected on the milestone 20-year anniversary of her Idol win.

"20 years ago today I won American Idol and it forever changed the course of my life," she began in a note.

"We only get so many trips around the sun and while I am proud and feel abundantly blessed of the successes and failures that I have learned from, I am most proud and grateful for those friends that have become family, and for their arms that have held me when I needed it and their hearts that listened to me when I felt lost. Without them I would not be where I am. I would probably not be here at all," she continued.

Following her Walk of Fame ceremony, she wrote in an Instagram caption that her star "is between Harry Potter and Deadpool ... I dare anyone to top that!"
