You need Demi Lovato to blow your mind.

Last night at Jessie J's concert in San Jose, California, the singer brought out Lovato to sing the Ariana Grande part of "Bang Bang." Naturally, the crowd went totally nuts. For what it's worth, neither of the women tried rapping Nicki Minaj's verse, instead opting to dance while her part played. 

Check out the fun below. 

Clearly, everyone had a great time.
