Mayor Bill de Blasio’s wife on Tuesday tried to counter a former fund-raiser’s damning testimony about her husband by saying Hizzoner’s “such a Boy Scout” that he’d never break the law.

First Lady Chirlane McCray also downplayed the extensive media coverage of the stunning allegations leveled by crooked restaurateur Harendra Singh at the ongoing corruption trial of former Nassau County Executive Ed Mangano.

“I think that’s tabloid news,” McCray told the Gotham Gazette’s “Max & Murphy” podcast.

“I think it comes and it goes. There’s always something, if it’s not play-to-pay it will be something else. That’s just the way the tabloids, specifically, how they operate. It’s always about taking something and how you pull somebody down.”

McCray also laughed while expressing unqualified faith in her hubby’s trustworthiness and obedience to the law.

“I am fortunate in that I married a Boy Scout,” she said.

“He is such a Boy Scout. He didn’t do anything wrong. I know he didn’t do anything wrong. He knows he didn’t do anything wrong. It’s just that you have to deal with that, that narrative that’s out there, figure out how to talk about it or not talk about it.”

“That’s just part of the work, really. But it’s not unsettling because I know it’s not true,” McCray added.

Singh secretly pleaded guilty in 2016 to bribing de Blasio with tens of thousands of dollars in campaign cash in exchange for a “favorable” lease extension on the Water’s Edge restaurant he formerly ran in Queens.

De Blasio was investigated by the feds for soliciting donations from various people who sought favors from his administration, but the probe was closed last year without any charges.

Since last week, Singh has testified that de Blasio encouraged him to use illegal “straw donors” to funnel campaign cash to political pals, saying: “Do what ever you gotta do, but I don’t want to know.”

Singh also testified that he used straw donors to make contributions to de Blasio.

The mayor has said of Singh: “This guy, to save his own skin, struck a plea deal with the federal prosecutors….He agreed to certain charges for his own self-preservation.”
