Demi Lovato Surprises Jessie J Fans By Filling In For Ariana Grande on “Bang Bang.” How Did She Do?

Let’s be real with ourselves for a minute— “Bang Bang” is probably the greatest pop tracks of the year (if not of all time). So the energy was already running high when Jessie J belted those first high notes during a concert in San Jose last night. But the singer took things to a different level when she brought out Demi Lovato to take Ariana Grande’s verse on the hit song.

The crowd predictably went crazy when Jessie J brought out her special guest, and Demi gave Ariana a run for her money with pitch-perfect precision. Sadly, neither diva took on Nicki Minaj’s rapid fire rap verse. But that’s probably for the best because our heads would have probably exploded from sheer pop awesomeness.
