In the video, McGraw is seen walking the catwalk into the crowd while performing "Truck Yeah" and high-fiving fans. At one point, a rambunctious woman appears to grab his leg and rip his jeans, causing McGraw to instinctively slap her in the face. Security quickly jumped in and pulled her away.  

 

 

Tim's rep tells TMZ, "Tim was singing out in the audience and someone firmly grabbed onto his leg and wouldn't let go as he was moving through the crowd. He instinctively swatted to try to keep them from ripping his jeans (which they succeeded at doing!), and so he could get to more fans who could slap hands with him before the end of the show."
