I already uploaded a first look on Queen Xtina singing on The Voice Season 10. But now that the Voice is over and Christina's contestant, Alisan Porter, is the winner, here's the full video on Christina Aguilera Singing / Coaching On The Voice Season 10

I also included:
Ariana Grande and Christina Aguilera - Dangerous Woman
I'm sorry but I wasn't able to include Christina's duet with a Whitney Houston Hologram
