Team Christina took to the stage to perform with their mentor tonight on 'The Voice' in an everything but the kitchen sink mash-up performance of fellow coach Blake Shelton's 'Hillbilly Bone' and Aguilera's own 'Fighter.'  They were even backed up by a high school choir.  It was as insane and bizarre as it sounds.

Before starting the theatrics, Christina took her team to a local Starbucks to talk about philanthropy.  Somehow the segment ended with Christina and her team watching a performance by the Crenshaw High School choir.  It didn't make much sense, but it was nice to see a more humanistic side of Aguilera.

Aguilera strutted out on stage in quite the racy outfit singing 'Hillbilly Bone' and throwing a wad of cash at Shelton.  She then stripped off more clothing to sing her early 2000's anthem 'Fighter.'  Flanked by a cadre of dancers, we saw glimpses of the pop star Aguilera was at her 'Dirrty' peak.  Ashley De La Rosa and Jesse Campbell rose from the crowd to trade lyrics on the verses with their fearless leader.

Things only got more busy as the first chorus hit.  Lindsey Pavao and Chris Mann came out from behind the stage with the large Crenshaw chorus behind them.  The last chorus found the multitude of voices playing background for the ebullient Aguilera.   Hugs and kisses were exchanged by the end, and this is an experience the high school choir will never forget.
