Is this Ghislaine Maxwell’s mystery husband?

Ghislaine Maxwell refused to cough up the name of her mystery husband to feds — but signs suggest it could be a British tech CEO.

Maxwell was most recently linked to divorced dad Scott Borgerson last year, when she was reportedly living at his oceanfront mansion in Manchester-by-the-Sea, Massachusetts.

But Borgerson denied the two were romantically involved in August.

Prosecutors said Maxwell used an alias — Janet Marshall — to purchase a sprawling estate in Bradford, New Hampshire, with a man who said his name is Scott Marshall.

A real estate agent told the FBI on Tuesday that the couple had British accents and told her they wanted to snap up the 156-acre property quickly through an LLC.

Scott Marshall described himself as retired from the British military and working on a book, prosecutors said. Janet Marshall, meanwhile, said she was a journalist.

The real estate agent later learned Janet Marshall’s true identity when she saw a photo of Maxwell in the media.

During Maxwell’s more than two-hour detention hearing Tuesday, Assistant US Attorney Alison Moe revealed Maxwell was married while discussing possible bail packages.

“In addition to failing to describe in any way the absence of proposed co-signers of a bond, the defendant also makes no mention whatsoever about the financial circumstances or assets of her spouse whose identity she declined to provide to Pretrial Services,” Moe said during the video proceeding, which was also held via teleconference.

Maxwell, 58, was previously linked to Ted Waitt, the founder of Gateway computers, until at least 2010, according to The Sun, which said she began dating Borgerson in 2013. The New York Times also reported on their romance.

She also dated Jeffrey Epstein — for whom she’s accused of recruiting and grooming young girls to be sexually abused.

Borgerson, 44, is a member of the Council on Foreign Relations and the co-founder and CEO of CargoMetrics Technologies, which specializes in analyzing data on global shipping, according to his Linkedin.

The online resume also indicates he spent four years in the US Coast Guard, as both a commanding officer and navigator, and worked as an assistant professor at the US Coast Guard academy.

Borgerson earned a Ph.D. from the Fletcher School of Law and Diplomacy at Tufts University and “has advised the White House on maritime policy,” the LinkedIn said.
