Videos posted on YouTube show Beyonce urging security guards who came to her rescue to be calm, People magazine reported. After she completed "Irreplaceable," she shook the man's hand, E! Online said.
"It's all right, it's all right," she told him, adding, "Nice to meet you. Thank you, I love you, too."
A security guard had to rescue Beyonce from a fan two months ago in Montreal, E! said. Her hair got pulled into a fan while she was performing "Halo" and, as she did in Sao Paulo, she kept on singing right through the incident.
