Watch ‘American Idol’ Judges Take a Trip Down Memory Lane (Exclusive)

Lionel Richie, Luke Bryan and Carrie Underwood are taking in some American Idol nostalgia.

In a clip premiering exclusively with PEOPLE on Wednesday, Dec. 31, the singing competition show judges are welcomed to Idol University by longtime host Ryan Seacrest.

“Welcome to American Idol University. With decades of talent on display, I’m so excited for you all to explore these historic halls,” Seacrest, 51, says, wearing a royal blue letterman’s jacket.

Then, the three judges appear in the highly decorated room wearing similar Idol University gear.

“Look at all of these superstars that have graduated from Idol-U,” Underwood, 42, says, as the camera shows framed photos of Idol alums like Kelly Clarkson, Jennifer Hudson and Jamal Roberts.

Richie, 76, adds “A dream come true in every direction.”

At one point, a display labeled “American Idol by the Numbers” is shown, showcasing the show’s awards and platinum records earned.

“What an incredible amount of lives that have changed,” Bryan, 49, says as he gazes at the displays.

“And hairstyles,” the “Before He Cheats” singer adds, before a framed wall of Seacrest’s hair evolution is shown.

At another point, the judges approach what they think is a wax figure of Clay Aiken, whom Bryan calls “one of the greats.” Then, Aiken startles them when he whips his head around and winks at the judges.

Finally, the judges approach a door that says “welcome 2026 Idols.”

“American Idol class of 2026 is in session,” Underwood says joyfully, before a teaser of the upcoming season plays.

To wrap up the video, Aiken appears once more and steals Seacrest’s line: “Who will be the next American Idol?”

“Um, that’s my line!” Seacrest says, walking into the frame.

American Idol season 24 premieres on Jan. 26 on ABC, with episodes airing next day on Hulu.
