Rudy Giuliani, who smeared Stormy Daniels because of her adult film career, has been caught in a sordid sex scandal with a married woman that appears to be the catalyst for his wife’s decision in April to file for divorce after 15 years of marriage.

The affair came to light before Giuliani, now one of Donald Trump’s lawyers, and his wife separated, according to The New York Post, citing multiple sources.

The woman has been identified as Maria Rosa Ryan, 53, a New Hampshire hospital administrator who is married to an ex-Marine. She is more than 20 years younger than her 74-year-old lover.

They were spotted together at a resort hotel in late March — a week before his wife of 15 years, Judith Nathan, filed for divorce, sources told The Post.

Giuliani was spotted again with Ryan when he showed up on Mar. 29 at the hospital she uns for a guided tour. Local ABC television news outlet WMUR, recorded his appearance. Giuliani claimed he was at the hospital to learn about its cybersecurity program.

On April 4, Nathan, 63, ended their 15-year marriage, according to court records.

Ryan lives with her husband, Robert, in Manchester, NH. But instead of heading home, she traveled an hour north to the Mountain View Grand Resort and Spa in Whitefield.

Giuliani booked the posh resort’s spacious Summit Suite. After dinner, “the woman went back to his room with him,” a waitress told The Post.

“We were all surprised because he is really getting on in years, and she was quite a bit younger than him. We were all like, ‘Hmmm,’ ” the server added.

Giuliani denied having an affair with Ryan, but admitted dining at the New Hampshire resort. He told The Post today:

“I do know Dr. Ryan. She is a friend of mine, so is her husband Bob. She’s a PhD and a very, very fine woman. I was in effect separated by then… I never spent the night with her. There’s no proof. There can’t be because we never did anything.”

Daniels’ lawyer Michael Avenatti called former Giuliani a “pig” after he said Daniels “has no reputation.”

“If you’re going to sell your body for money, you just don’t have a reputation,” Giulani said.

Trump lawyer Michael Cohen paid Daniels, real name Stephanie Clifford, $130,000 in October 2016, on the eve of the presidential election, to keep quite about her affair with Trump in 2006.

Daniels and Trump have since become embroiled in litigation over the allegations and a non-disclosure agreement Daniels signed but Trump didn’t.

Giuliani’s career has been rocked by sordid affairs and sex scandals. Nathan was his third wife, who began seeing Giuliani while he was still married to his second wife.
