All hail Christina Aguilera!

On the latest blind auditions for The Voice, the 35-year-old knocked the socks off her fellow coaches when she spontaneously went onstage to duet with young hopeful, Joe Maye, on the ‘50s rock classic, “I Put a Spell on You.”

“That is one of my favorite songs in the whole wide world to sing. I’d actually love to sing that with you one day,” Christina said before Pharrell Williams coaxed her into putting on a show for the crowd.

Of course, she and Joe nailed their mind-blowing performance -- as if any of us had any doubt. (Adam Levine, Blake Shelton and Pharrell sure didn’t!)

It had everything you’d want in a Christina duet: crazy runs, powerhouse vocals and all the emotion you could ever expect! “That was fun!” she said afterward.

But it was Joe’s enthusiastic reaction to what just transpired that may have been the cherry on top.

“Oh my god!” he screamed in excitement, as he jumped up and down onstage.

Not surprisingly, Joe picked Christina to be his coach over Blake. Welcome to Team Xtina!

Back in November, Christina forecasted that season 10 may finally be her year to take the crown.

“This could be the season, cross my fingers, that Team Xtina might take it,” she told ET. “I’ve got some pretty great talents.” With the way this season is shaping up, the boys better watch out.
