As Celebuzz reports, the 19-year-old singer was in the country Thursday for a show, and was talking to the crowd when her fans anticipated that she was going to let some of the audience up on stage. But before she could clarify her instructions, one fan hopped on stage and rushed over to Lovato, throwing her arms around her in a hug.

As security tried to remove that fan, others began to pour onto the stage as Lovato swiftly removed herself from the disruption.

The singer/actress didn't appear to be shaken, as she promptly came back out and requested that the audience "chill out." Thankfully, another song seemed to defuse the situation, and Lovato kept the night moving right along.

The former Disney star has also lined up a series of dates in the U.S. this summer, starting in Del Mar, California on June 12.
