Jessie J performed in San Jose last night and she brought out a very special guest for "Bang Bang".

It wasn't Nicki Minaj, or Ariana Grande.

It was Demi Lovato! Looking stunning in a matching black crop top and skirt, she sang Ariana's part in "Bang Bang". We've got to say, she did a pretty damn good job hitting all of Ariana's high notes.

You can hardly hear them over that loud roar of screaming fans!

It's 2014 so of course, bring on the backstage selfless!

 

been wanting to sing with you forever! Tonight was special @ddlovato #triplehoshow #sanfran #bayarea @997dolphin

Looks like Demi had a really good time. She tweeted Jessie that performing with her was "an honor".
