Beyonce Pulled Offstage by Fan During Concert in Brazil

Beyonce had the ring the alarm for real in concert at the Morumbi Stadium in Sao Paulo, Brazil on Sunday, Sept. 15 -- when an overexcited fan yanked the superstar offstage for a very scary few seconds. In an instantly viral video, Beyonce, 32, bonded with fans on the intimate "Bey Stage" -- a square platform surrounded by audience members on all four sides -- to croon her classic send-off ballad "Irreplaceable."

As Blue Ivy's mama held her mic out for fans to send along, one shirtless, burly guy in the audience grabbed Beyonce and pulled her down off the stage, with Beyonce nearly descending into the pit of fans. Security guards immediately stepped in and retrieved Beyonce from the fan's grasp.

Beyonce's reaction? Keep on singing in that bedazzled blue bodysuit, naturally! Not missing a beat, the Grammy-winning diva even acknowledged her creepy stalker in a friendly fashion, giving him a friendly handshake.

It's just the latest slight hiccup during Bey during her massive Mrs. Carter Show world tour; during the trek, she's also had her hair caught in a massive fan, and another acolyte smacked her famous posterior.
