‘American Idol’ Season 15 Spoilers: Kelly Clarkson Will Return For Final Season; When Will She Guest Judge?

Kelly Clarkson is returning to her roots. According to reports, the 33-year-old singer, who won the first season of “American Idol” in 2002, will appear as a guest judge during the final installment of the long-running Fox series.

Executive producer Trish Kinane announced the exciting news during the Television Critics Association press tour Friday.

"We've invited her to be part of this season and she's really happy to be," Kinane said, revealing Clarkson will perform and guest judge during Season 15's first live top 10 show on Thursday, Feb. 25.

But Clarkson, who is currently pregnant with her second child, isn’t the only “American Idol” alum set to take the stage during the show’s 15th and final season. Other winners throughout the history of the Fox competition will break out in tune as they partake in duets during the middle rounds with the remaining finalists.

"We're talking to everybody who's made a huge contribution to the show, and we'd love to have them come back," Kinane continued, adding that statement also applies to the talent that sat behind the judges' table. According to reports, it’s possible that the show’s original judges, Randy Jackson Paula Abdul and Simon Cowell, will reunite during the final season — that is, if there are no scheduling conflicts.

“I appreciate Simon’s part in the history of the show,” the EP said. “[But] there are huge scheduling issues. The most we can expect is for Simon to be at the finale.”

Hey, the show’s not over until the grumpy man sings! But Keith Urban, who has been hosting the competition since 2012, teased that just because Season 15 has been dubbed as the “farewell season” for “American Idol,” that doesn't mean its necessarily the end for the award-winning show.

"I think the Eagles have had at least three farewell tours," the country crooner quipped.

Season 15 of “American Idol” airs Wednesdays and Thursdays at 8 p.m. EST on Fox.
