Blake Shelton and Christina Aguilera Perform Emotional Version of ‘Just a Fool’ on ‘Ellen’
Blake Shelton and Christina Aguilera are co-workers, serving as coaches on 'The Voice.' But they also duet on 'Just a Fool,' a torchy ballad from her new album 'Lotus.' They performed an emotional, gripping and ultimately moving rendition of the song on 'The Ellen Show' yesterday (Dec. 7) and if we didn't know any better, we'd think there was something between the singers!
