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.
