It's crazy how even though that was a once in a life time opportunity to touch your favorite singer, but to touch them in private areas knowing that are married is a bit awkward. Yes, to most people the artist being married or not doesn't make a different, but out of respect for the artist at least touch their hand. However sometimes the artist do be close to the stage enough to touch them or rip off their clothes.
At the same time could the way they dress have a lot to do with it as well. When artist wear something very revealing a fan can't help to want to experience everything they are seeing. How often do you get to see your favorite artist in general especially touch them. No a fan shouldn't harrass them, but they can't help themselves when coming in contact with them. With that being said, was Beyonce the one to be blamed because of her choice of clothing or the fans.
