A Jeffrey Epstein accuser once claimed former President Donald Trump allegedly had “sexual relations” with one of her unnamed friends at the late pedophile’s New York home “on regular occasions,” according to another trove of court documents unsealed Monday.

Sarah Ransome, in a string of 2016 emails to then-New York Post columnist Maureen Callahan also claimed that she had copies of tapes Epstein had made of some of his high-profile friends — Trump, former President Bill Clinton, Prince Andrew and British business magnate Richard Branson — allegedly having sex with an unnamed woman.

“She confided in me about her casual ‘friendship’ with Donald. Mr. Trump definitely seemed to have a thing for her and she told me how he kept going on about how he liked her ‘pert nipples,’” Ransome wrote about her friend in one email, made public when the latest batch of newly unsealed documents dropped.

“I also know she had sexual relations with Trump at Jeffery’s NY mansion on regular occasions,” she added.  

Ransome walked back the salacious allegations in an Oct. 23, 2016 email with Callahan, writing, “I would like to retract everything I have said to you and walk away from this,” according to the filing. 

She added that “only bad things” and “pain for my family”  would come from going public.

In 2019, Ransome admitted in a New Yorker article that she “invented the tapes to draw attention to Epstein’s behaviour.”

Trump advisor Steven Cheung said in a statement Monday: “These baseless accusations have been fully retracted because they are simply false and have no merit.”

Clinton’s rep Angel Urena declined to comment Monday.

A Virgin Group spokesperson told The Post: “In a New Yorker report published in 2019, Ransome admitted that she had ‘invented’ the tapes. We can confirm that Sarah Ransome’s claims are baseless and unfounded.”

Ransome — who has been living abroad since at least 2017, and is now living in London — never produced the alleged sex tapes.

She didn’t immediately return a request for comment Monday.

The emails were filed in a since-settled defamation lawsuit case that Epstein accuser Virginia Giuffre — aka Virginia Roberts — had brought against the sicko’s madam, Ghislaine Maxwell, in 2015.

The messages were disclosed as former Harvard Law School professor Alan Dershowitz’ lawyers were seeking to undermine Ransome’s claims, arguing that “she manifestly lacks credibility.”

Dershowitz, Epstein’s one-time lawyer, had been accused by Giuffre of sexually abusing her in a lawsuit she has since dropped admitting she “may have made a mistake.”

In a letter to the judge at the time, Dershowitz’ legal team had argued that if Ransome’s deposition were to be made public, her emails should, too, because without the added context her “unrebutted testimony will gravely prejudice [Dershowitz] by publishing deliberate lies calculated to harm his reputation.”

“The deposition transcript standing alone leaves an incomplete and, thus, false impression of Ms. Ransome and her outrageous claims,” the letter read.

“This court should not allow its power to enter and modify a protective order to be manipulated so as to authorize selective disclosure of de-contextualized materials. If the Ransome deposition is made public, the Emails must also be as well.”

The 17 documents — totaling 327 pages — released Monday add to the avalanche of information that has emerged in recent days detailing how the late pedophile leveraged his connections to the rich, powerful and famous to recruit young girls and cover up his crimes.

In addition to high-profile names, the documents contain the accounts of some of Epstein’s teenage victims, as well as those who once worked for the late financier.

Among the details to emerge in the newly unsealed docs released last week were allegedly that Prince Andrew “spent weeks” at Epstein’s Palm Beach, Florida, mansion, where the disgraced royal would receive “daily” massages.

A girl, identified only as Jane Doe 3, also accused the Duke of York of engaging in an “orgy” with underage girls during one of his stays on Epstein’s private island in the Caribbean, according to a court filing.
