A video of a fan slapping Beyonce's butt at Monday's concert in Copenhagen has gone viral.

While the 31-year-old singer was performing her hit-single, Irreplacable, she walked on the stage to interact with her fans. She knelt down to allow a male fan to sing a verse of the song in her microphone. As she got back up to her feet and turned away, the fan slapped her butt.

The singer didn't let the fan get off easy and said to him in front of the huge crowd: "I will have you escorted out right now, alright?"

Moments later, she continued on with her performance.

This is not the first time the singer was slapped by a fan during a concert.

Enstars reported in April that while the Love on Top singer was walking through the crowd at the opening concert of her tour stop in Belgrade, Serbia, one spectator reached over the barricade and hit Beyonce in her head. The singer's bodyguard, Julius escorted her from behind and attempted to help move the singer through the mob, but couldn't do much to help as other fans touched and even pulled Knowles' hair.

Beyonce is in the middle of her Mrs. World Carter World Tour and the set of shows have been filled with strife and drama.

Earlier this month, the singer was forced to cancel one of concerts in Belgium, due to illness. At the time, she penned an apology to her fans and asked for their forgiveness.

"I've never postponed a show in my life. It was very hard for me. I promise I will make it up very soon. I'm sorry if I disappointed you. Thank you for your concern. I'm feeling much better now and I'm ready to give you a great show. All my love. See you tonight," she said in the letter.  

Pregnancy rumors soon started to swirl after the concert cancelation, as E! News reported that the singer was expecting her second child with husband, Jay-Z.

Beyonce has yet to confirm whether or not she is pregnant.
