Demi Lovato surprised unsuspecting fans in Atlanta last month with a live performance of her latest single, 'Give Your Heart a Break,' as a part of VEVO GO's concert series.

The 19 year old was scheduled to perform at the Cobb Energy Center that evening, but gave lined-up Lovatics the thrill of a lifetime when she appeared on an 18-wheeler to sing her 'Unbroken' track. "I’m actually really nervous right now, because I’ve never done a 'Go' show and I've never done an unannounced show before, so this will be my first surprise show," the pop star says before her pop-up performance.

Lovato sang her supportive single to a crowd of screaming fans, while wearing a hat atop her fiery red locks. 'Give Your Heart a Break,' is the second official single from the star's third studio album, following her inspiring hit, 'Skyscraper.'

The impromptu show may not be Lovato's last. She enjoyed herself so much, that she's entertaining doing another concert like this in the future. "I would love to do that again," she says at the end of the clip. "A surprise show would be really, really fun, and I think that it turned out to be a success, so I'd love to do it again."
