Beyonce almost had her set interrupted at a concert in Copenhagen, Denmark last night when an audience member decided to slap her on the butt.

It's not uncommon for fans to reach out and touch their favorite singers during a show. But this inappropriate move prompted Bey to stop singing her hit 'Irreplaceable' and point out her aggressor. "Now I will have you escorted out, alright," she said.

A video of the incident was filmed by a fan, who uploaded the slap to YouTube.

As they say, "the show must go on," but it's not easy to do so when you're violated in this way. So props to Bey for keeping her performance going.
