(popmusiclife) The Voice coaches Christiana Aguilera and Blake Shelton teamed up to perform a duet on the Ellen DeGeneres Show.
The pair sang "Just A Fool" from Christina's new album, "Lotus." Aguilera also sat down with Ellen to chat about her new project, her love of celebrating the holidays, and The Voice.
"It's our third season in," said Christina. "As coaches, we kind of hit our stride, we get what it's all about: we're invested in our teams. I'm sitting next to Blake the whole time so how can I not laugh
between him and Cee Lo [Green] with his gas over there and then there's Adam over there very competitive." Watch video from the appearance here.
