New Jersey Gov. Chris Christie got in the face of a Chicago Cubs fan in Milwaukee on Sunday — all while keeping an iron grip on his bowl of nachos.

Christie was walking down the aisle, snack in hand, when he was razzed by a Cubs fan, according to footage tweeted by WISN.

He got into a brief stare-off with the fan, faces about a foot apart, before Christie sarcastically told him: “You’re a big shot!”

The Cubs fan nonchalantly replied: “I appreciate that.”

The confrontation happened seconds before Victor Caratini, a rookie backup for the Cubs, blasted a seventh-inning, tie-breaking homer. The Cubs won, 4-2.

This was the second time in less than two weeks the remarkably unpopular governor has caused a ballpark stir.

He caught a foul ball at a Cardinals-Mets game at Citi Field on July 18 and eagle-eyed Amazins fans immediately identified him — and unleashed a chorus of boos.

Christie is in Milwaukee this weekend visiting his son, who works for the Brewers.

And this wasn’t the first snack-in-hand brouhaha that Christie’s had, caught on tape.

Back in 2012, the governor — while enjoying an ice cream cone on a Seaside Heights boardwalk — shouted a passerby, who made an unkind remark about his education policy.

“You’re a real big shot,” Christie yelled, not losing a drop of ice cream. “You’re a real big shot shooting your mouth off.”
