John Mellencamp's two teenage sons have been charged with felony battery amid allegations they beat up another man in Bloomington, Indiana. The legendary rocker's boys, Speck and Hud, reportedly became embroiled in an altercation with a 19 year old outside his home on 29 July (13). Police claim the pair, alongside pal Ty Smith, kicked and punched the male until the victim's roommates heard the attack and ran to help. Cops were called to the scene, but according to the official incident report, no arrests were made at the time as no one present wanted to pursue criminal charges. The Mellencamp boys reportedly told officers they had lashed out in relation to an incident that took place at a party earlier in the night, when 18-year-old Speck had been hit in the face. Their alleged victim was hospitalised with fractures to his face and required stitches for cuts. Charges against the Mellencamps were filed on Thursday (15Aug13) and Speck and 19-year-old Hud, a trained boxer, are now both facing a count of battery resulting in serious bodily injury. Smith, the son of Indiana University baseball coach Tracy Smith, has also been charged with felony battery for his part in the alleged fight. News of the altercation comes just weeks after John Mellencamp appeared on late night TV in America sporting a black eye. During the June (13) interview with David Letterman, he explained, "My son and I had words and he got a punch in and I didn't. (He's) 18. He's 6'2 and weighs almost 200 pounds..." Speck and Hud are the singer's two children with his third ex-wife, former supermodel Elaine Irwin Mellencamp.
