Kenny Chesney's concert at Heinz Field in Pittsburgh this past Saturday ended with fans getting rowdy, fighting, and getting arrested!

Nearly 80 people were arrested for offenses including disorderly conduct, public intoxication, and aggravated assault! Another 45 fans were taken to nearby hospitals.

Isn't his saying "No Shoes, No Shirt, No Problem?" Guess that was NOT the case here!
