There was a concert in Serbia. In the video it looks as if the fan touched the top of her head and then slid down her face and hair. Watch for yourself. The media is so overrated! Always blowing things out of proportion. OMG if a fan slapped Beyonce trust, her security team would've effed somebody up!
Seriously there is nothing to this story beyond that! Honestly people will make a mountain out of a mole hill. Absolutely ridiculous!
