Jill Biden helps escort a protester out of Joe Biden's campaign event in New Hampshire.

Jill Biden played bouncer for her husband, Joe Biden — helping to eject a heckler who tried to disrupt his rally in New Hampshire.

“I’m a good Philly girl,” she later told reporters, laughing.

The former vice president had just begun speaking during the rally on the eve of the first-in-the-nation Democratic primary when the man began to walk toward the podium in Manchester, CNN reported.

The protester, who was shouting while recording the moment on his cellphone, was met with shouts from the former Delaware senator’s supporters, some of whom tried to block his path.

Jill Biden, 68, quickly jumped into action, walked over to the heckler and helped others keep him from getting too close to her hubby before he was ushered out.

The former second lady has become one of Biden’s most forceful surrogates on the campaign trail, where she often serves as a closer for his speeches as well as headlining her own events.

“Joe and I’ve been married for 42 years. This is how we’ve always done things. I’ve campaigned in every election,” she has told CNN. “I go one way, he goes the other way, and so we can cover more ground and talk to more people.”

Monday night’s incident comes as Biden, 77, faces what’s expected to be an underwhelming showing in the New Hampshire primary Tuesday following a poor result in the Iowa caucuses.

Meanwhile, Vermont Sen. Bernie Sanders holds on to his lead, according to the final CNN tracking poll conducted by the University of New Hampshire Survey Center.

In the final numbers, 29 percent of likely primary voters say they back Sanders, 22 percent back Pete Buttigieg and 11 percent support Biden, who for months polled well above the rest of the crowded Democratic field.
