Kelly Clarkson clearly has closed the book on “American Idol” … her go-to is now “The Voice.”
We got Kelly in NYC where a hopeful soul busted out in song for the OG ‘Idol’ — her song, of course — and Kelly seemed impressed.
Check out the clip — he might have a future with an assist from Blake Shelton and friends.
Kelly even reminisces on her old friend Justin Guarini … wherever he is.
