Demi Lovato Suprises Fans With Live 'Give Your Heart a Break' Performance for VEVO G

Demi Lovato gave fans the surprise of a lifetime when she appeared on an 18-wheeler outside the Cobb Energy Center in Atlanta last month, performing her latest single, 'Give Your Heart a Break,' as a part of VEVO GO's concert series.
   The event was filmed for all of her fans to see, and is now available online, complete with behind-the-scenes interviews. "I'm actually really nervous right now, because I've never done a 'Go' show and I've never done an unannounced show before," Demi said before her big surprise appearance.
