Kelly Clarkson Accidentally Forgets Clay Aiken Didn’t Win His American Idol Season: ‘So Sorry, Ruben’

Kelly Clarkson is looking back on the American Idol days — and accidentally fudging some crucial details.

When friend and singer Clay Aiken, 46, stopped by The Kelly Clarkson Show on Monday, Dec. 16, the reality show alumni — naturally — discussed their time on the hit series, and Clarkson, 42, forgot that Aiken did not actually win his season.

“So we spent a lot of time … we toured,” the season 1 champion began, referring to the singers’ 2004 co-headlining Independent Tour that followed the first two seasons of American Idol.

“I won the season before you, but we toured after you won,” she continued, inspiring a surprised look from Aiken, who came in second to season 2 winner Ruben Studdard.

The Christmas Bells Are Ringing musician’s eyes went wide, darting back and forth after the host’s false declaration. “After I came in second,” he kindly corrected, as a stunned Clarkson replied, “You what?”

Realizing her mistake, the “Since U Been Gone” singer immediately — and hilariously — turned to the camera to rectify it by apologizing to Studdard, 46.

“So sorry, Ruben. I totally remember that,” she said, inspiring laughter from both the audience and Aiken.

After some reminiscing on their American Idol and touring days —  from heated Scrabble matches to clashing over Aiken’s refrigerator organization — Clarkson brought up the “winning thing” once more.

“See, now I actually did win,” she began, as Aiken interjected: “’Cause you did win. Yes. I remember that as well.”

“But I don’t know if you remember this and you probably do, but no one cared that I was there [on the 2004 tour],” Clarkson said as her guest objected. “No one!” she doubled down. “That whole tour.”

And, after getting confirmation from Jason Halbert, a current member of her house band who was also on the tour, she added, “I’m telling you, it was as if I didn’t exist.”

“You exist now, darling,” Aiken added, inspiring a smattering of supportive applause.

Elsewhere in the episode, the pair discussed Aiken’s sweet friendship with Studdard — the season 2 winner and runner-up also united on Broadway in 2018 for Ruben and Clay’s Christmas Show — with Aiken assuring that he is “sure” he and Studdard will “do stuff again.”

“I mean, we’re sort of inseparable,” he said. “I think we’re better together than apart.”

Clarkson, meanwhile, called the pair an “odd couple” but one that “so works.”
