The pal believes the hidden marriage — a bombshell revelation at Maxwell’s court hearing — was likely orchestrated “to protect the money she had,” the Times UK reported.

Prosecutors say the British heiress is linked to 15 different bank accounts, some with balances of more than $20 million, and that she keeps other accounts in foreign countries containing more than $1 million.

Jeffrey Epstein’s accused madam also snagged $15 million on a sale of an unidentified residence in New York City in 2016, prosecutors said.

When the pal last saw Maxwell two years ago, Maxwell was tight-lipped about her living situation.

“I asked her where she was living and she wouldn’t tell me,” the pal told the outlet. “She said, ‘A little bit of everywhere.’”

Another former friend of Maxwell said she was completely unaware of the British socialite’s secret nuptials.

“No one knew she was married,” the ex-chum told the outlet, adding that she had been in a relationship for a while with the tech entrepreneur Scott Borgerson.

“I don’t know of any other guy who she has actually seen.”

Maxwell was arrested earlier this month on a six-count indictment charging her with recruiting and grooming young women to be sexually abused by both her and Epstein.

She was ordered held without bail on Tuesday.
