Beyonce was slapped once again by a fan, but this time she was hit on her rear-end.

During a concert in Copengahen on Monday, the 31-year-old singer took to the stage to perform her hit-record, Irreplacable. Beyonce went in to the crowd to interact with the audience and bent over to allow a male fan to sing a verse from the song. As she walked away, the fan slapped her on the butt.

The singer turned around, seemingly angry and said in the below video: "I will have you escorted out right now, alright?"

The incident didn't stop her groove, as she continued with her performance.

Unfortunately for the Bow Down singer, this is not the first time she has been hit by a fan.

 Enstars reported back in April that as she 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 tried to help move her through the mob, but couldn't do much to help as other fans touched and pulled her hair.

The Mrs. Carter World Tour has been a roller coaster for the singer. After she was forced to cancel her concert early this month, due to sickness, rumors swirled that she was expecting another baby. Her husband, Jay-Z, reportedly defended her and said that she is not pregnant.

Last week, Hot 97 Program Director Ebro Darden said on the radio's morning show that he emailed the Watch The Throne rapper to offer his congratulations on the baby news.

"I emailed on some congratulations, send my love to the family, blah, blah, blah," he said, but noted that Jay-Z responded short and straight to the point.

"It's not true. The news is worse than blogs," the rapper allegedly said in an email.
