Giuliani denied the affair to The Post, although he added that the dinner and movie he shared with Ryan at a posh spa March 29 - five days before Nathan filed for divorce - occurred when he "was in effect separated".
President Donald Trump's attorney Rudy Giuliani is seen during a visit at the Hadassah Medical Center in Jerusalem on June 7.
Page Six says that Rudy Giuliani was having an affair with a married woman, Maria Rosa Ryan, while he was still living with Nathan.
Giuliani, 74, had an alleged affair with Maria Rosa Ryan, 53, who is married to an ex-marine.
A source questioned Giuliani's story and noted the mayor, who is said to have met up with Ryan on the campaign trail, was also in New Hampshire Memorial Day weekend.
He eventually held a press conference to announce his plans to separate from Hanover, a moment which he became widely criticized for as she claimed that he did not inform of the press conference before hand, effectively causing her to find out the he was planning to file for separation at the same time as the public. A waitress for Giuliani, Ryan, and three other men dining with them told the Post that "the woman went back to his room with him".
Employees at the resort say that the two stayed together in a suite with a mountain view.
"We were all surprised because he is really getting on in years, and she was quite a bit younger than him".
The resort staff said that Giuliani was friendly and that the two watched a movie in the private screening room (The Godfather). "We were all very impressed".
Giuliani said he knew the split was coming - but insisted it wasn't because of any hanky-panky with the married Ryan, who is the CEO of Cottage Hospital in Woodsville, N.H. "She's a PhD and a very, very fine woman", Giuliani, a former federal prosecutor and onetime Republican presidential candidate, told the Post Tuesday. "There's no proof. There can't be because we never did anything".
