The singer was performing "The Mrs. Carter Tour" that night at Morumbi Stadium in Sao Paulo.
During her 2007 tune "Irreplaceable," she moved to a smaller stage in the middle of the crowd, Billboard reported, at one point leaning down to shake hands with those in the front rows. She got more love than she expected, however, when a shirtless man grabbed her and pulled her toward the amassed people.
Watch the video above to see security rush to Beyonce's aid, hauling the singer back to performing position, where she barely missed a beat.
She even returned to the scene of the exuberance, shaking hands with the guy and letting him know everything was cool.
Bey has one more date in Brazil, in Brasilia on Tuesday, before heading to Venezuela, Colombia, Mexico and Puerto Rico. October will see her Down Under, in Australia and New Zealand.
