(USA TODAY) -- This is what can happen when you reach out to your fans.
While performing at the Morumbi Stadium in Sao Paulo, Brazil, on Sunday, Beyoncé was happily singing and swinging her hair around when she stooped down to shake hands with fans who were right at her feet at the edge of the stage.
In an instant, one of them jumped up and pulled her down. It looks pretty startling in a video posted on YouTube. A security guard immediately ran up on stage and grabbed her to pull her back up.
Beyoncé seemed unfazed and kept right on singing Irreplaceable throughout it all. Later she even spoke to the fan saying, "It's all right. ... thank you, I love you, too."
