Weiner’s wife puts on brave face amidst Twitter-photo scandal

She’s standing by her man — but that act seems to be wearing thin.

Rep. Anthony Weiner’s humiliated wife sheepishly showed her face at a Washington event yesterday, keeping a stiff upper lip amid the swirling scandal surrounding her husband’s tawdry Twitter photo.

Huma Abedin, 34, briefly hesitated at the State Department ballroom door before working up the courage to go in — but she left after just five minutes and steered clear of her boss, Secretary of State Hillary Rodham Clinton.

While she put on a brave face inside the Beltway, her husband was busy weaseling out of a long-scheduled speaking engagement at last night’s Wisconsin Democratic Convention.

“He told us this morning” that he was canceling his appearance, said Graeme Zelinski, spokesman for the state’s Democratic Party. “My understanding is he’s going to spend the weekend with his wife in New York.”

It seems like a good call, as Abedin’s wounds still looked fresh yesterday.

At first, she seemed to be a no-show at Clinton’s morning event, where the secretary hosted a session of the Iraq Business Roundtable for companies including Caterpillar, FedEx, Microsoft, Citigroup and GE.

But shortly after the event began in the ornate Ben Franklin room, Abedin opened a door, peered into the room, then strode over to another Clinton aide 20 feet away from the secretary.

Wearing a black pant suit and a prominent pearl necklace, Abedin never cracked a smile and kept her distance from the former first lady. She ducked out long before the event finished.

Abedin wed Weiner, 46, last July in a ceremony conducted by former President Bill Clinton — himself an expert on seedy political sex scandals.

She has kept a very low profile since it was revealed last week that a pretty young Washington state woman received a photo of an erect penis, covered by a pair of briefs, from Weiner’s Twitter account.

A State Department source said Abedin actively participated in a departmental meeting Thursday — as her husband’s scandal was escalating.

“She’s working hard,” said the source.

Weiner has adamantly denied being the peter tweeter, claiming his account had been hacked.

But he bizarrely said he could not say with “certitude” that the photo of the bulge in the briefs wasn’t his.

Weiner grimly refused to say more about the crotch contretemps as he stalked out of his House office yesterday.

And he brushed off a question about how “Weinergate” had left Abedin feeling.
