It’s been nine years since Christina Aguilera and Blake Shelton performed “Just a Fool” on The Voice when they were both coaches. On Friday (Feb. 12), Kelly Clarkson took the stage of her own talk show to pull off the duet all on her own.

She stripped down the country-pop ballad on the dimly lit stage with only The Kelly Clarkson Show‘s musical director Jason Halbert playing the piano. Clarkson powered through Aguilera’s first verse before taking on the swelling chorus.

Kelly Clarkson Says Blake Shelton Leaving 'The Voice' Is a 'Gain'

“I, I had my heart set on you/ But nothin’ else hurts like you do/ Who knew that love was so cruel/ I waited and waited so long/ For someone who’ll never come home/ It’s my fault to think you’d be true/ I’m just a fool,” she sang while hitting the high note in the titular line.

“Just a Fool” was featured on Aguilera’s seventh album Lotus from 2012. Aguilera and Shelton promoted the song by performing it live on The Voice during its third season on Nov. 19, 2012.
