A fan got a little too cheeky with Beyonce in her concert on Monday night. The singer threatened to have the concertgoer thrown out after he slapped her in the butt on stage.

The incident took place at Beyonce’s Copenhagen leg of her Mrs Carter Show world tour at The Forum. She was performing her hit “Irreplaceable,” encouraging her fans to join her sing the line “to the left.”

As she got to the smaller stage so she can easily reach her fans and hand them the microphone, one fan boldly slapped her on her butt.

The music suddenly stopped and Beyonce addressed the man, giving him a stern warning, “I will have you escorted out of here.”

It isn’t known if the man was truly escorted out of the premises.

Beyonce, who is married to rapper superstar Shawn “Jay-Z” Carter, kicked off her Mrs Carter Show world tour in April in Serbia, and will conclude it in Brazil in September.

Meanwhile, it has been reported that Beyonce is expecting her second child. The 31-year-old Grammy winner ,who gave birth to daughter Blue Ivy in 2012, is rumoured to be pregnant while she’s on tour.

However, Jay-Z denied the speculations, telling radio station Hot 97 in an email that “it’s not true.”
