Demi Lovato gave some of her fans a big surprise when she performed before a concert last month.

Lovato teamed up with VEVO to take part in a pop-up show as part of the VEVO Go Shows.

The surprise performance, where the 19-year-old performed her new single off her hit album, Unbroken, called Give Your Heart a Break, took place last month in Atlanta before an official Demi Lovato concert.

According to Pop Crush, the Skyscraper singer performed in front of fans, who were waiting in line outside the Atlanta venue. The surprise came when an 18-wheeler pulled up with a stage and Lovato ready to perform.

Im actually really nervous right now, because Ive never done a Go show and Ive never done an unannounced show before, so this will be my first surprise show, she told VEVO prior to her performance.

The singer said the screams and excitement she heard from her dedicated Lovatics turned the nerves into excitement, and after the experience, shed want to do it again.

I would love to do that again, she said. A surprise show would be really, really fun, and I think that it turned out to be a success, so Id love to do it again.
