The "If you want it, put your ring on it" singer, was slapped on her derriere while singing her hit song "Irreplaceable".

The daring fan performed his playful move in Copenhagen last night. Jay-Z's wife threatened faithfully and warned the man that he would be escorted out of the concert for his behavior.

The man lucked out and did not have to leave the premises.

The mother of one picked out singers from the crowd like she had previously successfully done. During her tour in London, she picked out Princess Eugenie unknowingly. The singer gave the 6th-in-line-to-throne woman a personal performance.

In Manchester, she also performed with former X Factor winner Joe McElderry.

The overzealous fan last night was also given his chance as a singalong.

Rumors have been circling that sexy diva is pregnant with another child. However, such rumors have been rejected after she has resumed her tour.
