Christina Aguilera, Blake Shelton Unveil 'Just A Fool' on 'The Voice'

Christina Aguilera features two of her fellow "The Voice" coaches on her latest record "Lotus" (released Nov. 13) and has used the show to showcase both collaborations -- this week proving that less is more with her country-pop duet "Just A Fool" with Blake Shelton.

For the performance, the two superstars kept things clean and classy starting at opposite sides of the stage before coming together centerstage on the shared second chorus. Aguilera kept her signature belting to a minimum but being in her presence seemed to bring out a few (unnecessary) ad-libs from Shelton. Looking sharp in dark, semi-casual outfits the two celebrated the end of their performance with a hug and high-five.

"Just A Fool" was announced to be the official second single from "Lotus" by a promotinal RCA Twitter account last week -- a smart move seeing the track raced up digital retailers upon release making it a contender for a Hot 100 debut this week and possibly rise higher following this performance.

Yet "The Voice" always focuses on the actual voices and, most importantly, Aguilera and Shelton nailed their parts setting a standard that the show's Top 10 finalists followed.

Standouts of the night included contestants Team Blake contestant Cassadee Pope's rendition of Miranda Lambert's "Over You," the emotional track that Lambert and Shelton won "Song Of The Year" at the CMA Awards this month. The track topped iTunes Top Songs chart and saw Lambert's version zoom up the charts. As well, Team Adam's Amanda Brown belted out Grace Potter & The Nocturnal's "Stars" with both her and the original version racing up to the top tiers on iTunes Top Songs chart making it a possibility for the band's first Hot 100 appearance is strong sales continue.

Aguilera made a loud statement with her Marie Antoinette circus-inspired performance of "Make The World Move" last week with Cee Lo Green. While the track is an encouraging, up-tempo number with an atypical chorus structure, "Just A Fool" is a classic heartbreak duet (that recalls the Kid Rock/ Sheryl Crow hit "Picture") that could prove to be a big hit this winter with its debut performance nicely setting up future chart success.
