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.
