In the middle of her set, Lovato motioned to her fans in the wings to move a little closer to the stage. Apparently, a bunch of those kids took the invitation a little too far, and surged forward.

Security separated the singer from her adoring fans and escorted Lovato offstage. Eventually, order was restored, and Demi returned to perform another song.
