Ashton Kutcher's trip to the Stagecoach country music festival was cut short when he got into a scuffle with a security guard on Saturday. According to TMZ, the incident occurred when the jOBS actor went to greet a fan while checking out sets by Nick 13 and Dwight Yoakam. Sources tell the website that as the female fan approached to shake Ashton's hand, a security guard intervened and began shoving both of them. Kutcher allegedly did not respond well to the situation and they began shoving each other violently until Ashton's friends had to restrain him. The guard reportedly demanded that Ashton be removed from the festival but he left on his own. Witnesses say the security guard was completely at fault for instigating the fight.
