Fan slaps Beyonce's butt during concert (VIDEO)



A Danish fan must not know 'bout Bey, he must not know 'bout Bey -- until now, that is.

Over the weekend at a concert in Copenhagen, superstar performer Beyonce was singing "Irreplaceable" and reached out to touch the hands of a group of her fans that were next to the stage. As she turned around, a fan reached up and slapped her world-famous booty.

"I will have you escorted out right now, alright?" says Beyonce, as she whirls around to confront said fan.

That's right, kid.

Beyonce's "Mrs. Carter Show World Tour" continues in Europe through the end of this week, then picks back up in North America on June 28.
