AMERICAN Idol runner up Bo Bice might be getting a bit full of himself.


According to NY Post, on Sunday night at O'Brien's Pub on West 46th Street, witnesses say the Southern rocker took a swing at strapping ex-New York Giants football star Glenn Parker!


The long-haired singer risked getting his block knocked off by the former offensive lineman. It all began when star-struck Parker casually approached Bice to chit-chat.

"Glenn had noticed Bo and simply asked him if he was really Bo Bice - and Bo just stared at him and said, 'No, I'm not. My name is Kevin.' It was weird," our witness said. "Glenn went away, but he started feeling like he might have imposed on the guy. So he went back to him to apologize for causing any discomfort."

Parker, 39, 6-foot-5 and 300 pounds has crushed many an opponent during his 13 years in the NFL with the Giants, Buffalo Bills and Kansas City Chiefs and everybody else in the popular watering hole couldn't believe what happened next.

"Bo just went at him with his fists - maybe he thought he was Simon Cowell or something, but he tried to hit him," our observer reports. "Glenn grabbed his arms to block the punches, but Bice broke loose and managed to graze Glenn under the chin. It was crazy because Glenn could have wiped the floor with him."

Possible not one of Bo's brightest moves!!!
