A fan in Copenhagen, Denmark, did what no one thought was a good idea when he reached out and slapped Beyonce on her backside during her concert on Monday.
It's all captured in a video on YouTube appropriately titled "The stupid guy that slapped Beyonce." As the singer strutted down the stage singing her song, "Irreplaceable," a man standing in the front row joined in for part of the chorus. "To the left, to the left, everything you own in the box to the left ..."
As Beyonce withdrew the microphone and began to retreat back upstage, the man reached out and gave JAY-Z's WIFE a slap on the rear.
"I will have you escorted out of here now ... all right?" Beyonce says to the man before launching back into the song. Here's another view from another YouTube video.
