Demi Lovato Sings 'Bang Bang' Live with Jessie J - WATCH NOW!

Talk about one amazing surprise – Demi Lovato hops on stage to join Jessie J on her song “Bang Bang” live in concert at the 99.7 NOW!’s 2014 Triple Ho Show on Wednesday (December 3) at the SAP Center in San Jose, Calif.

The ladies were both on the lineup at the concert, but Demi made the crowd go wild during Jessie‘s set by joining her for “Bang Bang” and singing Ariana Grande‘s verse as a super cool surprise!

Of course, the crowd went absolutely wild and it’s almost hard to hear her sing in the video captured at the concert.

“????????????… That just happened….. Thank you SO much @JessieJ for having me on stage for Bang Bang… It was an honor!” Demi tweeted.

    Demi has the better voice by far. Ariana, although good, only appeals to some. Like Mariah Carey. I’ll pass.

    Demi Lovato does Ariana Grande better than Ariana Grande does Ariana Grande.

  • Louise

    Demi lovato would have by far been a much better choice.

    I think they both have their strengths and weakness. Ariana Grande has better range and a high octave but for a live singer I can barely understand what she’s saying. That and she sounds like the air had been sucked out of her lungs whenever she sings her part in these songs. Demi While not having as high as an octave can at least sing the verse without sounding like a she has a bag of marbles in her mouth and has a much better control of her vocals. For this performance at least.
