WATCH: Demi Lovato Joins Jessie J on Stage for Duet of "Bang Bang"

by at .

Jessie J ran into a slight problem last night in San Jose, California.

She was performing at 99.7 NOW! 2014 Triple Ho Show, but the artist was doing so without Ariana Grande and Nicki Minaj.

So... how would she possibly entertain the audience with a rendition of the smash hit "Bang Bang?" Easy: she would bring Demi Lovato out on stage along with her. Much to the EXTREME delight of those in attendance.

"That just happened….. Thank you SO much @JessieJ for having me on stage for Bang Bang… It was an honor!" Lovato Tweeted soon after the pair brought down the hour with their duet.

Replied Jessie J after posting a clip from the performance on Instagram:

“WOW!!! @ddlovato is a dream to be on stage with!!! Thank you girl!!! You sang yo ass off!!! #bangbang @997dolphin @997now #triplehoshow.”

It sure looks like Lovato has a new friend in the business, doesn't it?

The timing is interesting, as well, considering Demi recently went public with the fact that her relationship has soured with Miley Cyrus.

"We're like...we're acquaintances," Lovato said in a radio interview. "It's life and people change and I don't have anything in common with her anymore, and I wish her all the best."

It's clear, however, that Lovato and Jessie J have a lot in common. We want more collaborations between these two!
