Bo Bice is not nice.

At least that’s the impression he undoubtedly left on ex-New York Giants football player Glenn Parker after a run-in with the athlete at O’Brien’s pub on Sunday night, reports today’s Page Six of the New York Post. For reasons unbeknownst to just about anyone, the lineman approached the American Idol finalist in the hopes of striking up a conversation.

"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," said a witness who tattled to the Post. "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."

And while some might have considered this gesture thoughtful and considerable, Bo apparently did not, attempting to punch the significantly-larger football player.

"Bo just went at him with his fists - maybe he thought he was Simon Cowell or something, but he tried to hit him," the same source reveals. "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." (For those of you unfamiliar with Glenn Parker, he stands 6 feet, 5 inches tall and weighs in at 300 pounds). Workers at O’Brien’s quickly stepped in and threw Bo out.

"He was a real pain in the ass," a bar employee was overheard saying. And something tells me it’s the real thing.
