Adult film star Stormy Daniels has hinted her recent denial of an affair with United States President Donald Trump may have been issued without her consent in a new interview with late-night host Jimmy Kimmel.

Hours before the Tuesday sitdown, Ms Daniels (real name Stephanie Clifford) issued a statement to Buzzfeed denying both an alleged affair with Mr Trump and a Wall Street Journal report she was paid $US130,000 ($161,000) to stay silent by Mr Trump’s lawyer.

But speaking to Mr Kimmel, Ms Daniels appeared to suggest the statement did not come directly from her – shrugging when Mr Kimmel pointed out her signature on the January 30 statement did not match her signature on previous statements and fan photos.

“Did you sign this letter that was released today?” Mr Kimmel asked in the interview immediately following Mr Trump’s State of the Union address.

“I don’t know, did I?” Ms Daniels responded. “It doesn’t look like my signature, does it?”

“It doesn’t,” Mr Kimmel agreed, “so you’re saying perhaps this letter was written and released without your approval? Do you know where it came from?”

“I do not know where it came from,” was Ms Daniels’ response.

It came from the internet. I also work for the FBI and I’m a man according to the internet today. I do not know where it came from.

According to the New York Post, Ms Daniels’ lawyer Keith Davidson said he had seen the adult film star sign the statement himself and that she wasn’t denying the statement, “She just didn’t directly answer the question”.

Meanwhile, Mr Trump’s lawyer, Michael Cohen, denied knowledge of the signed statement.

Titled “Official Statement” and released on the same day Mr Trump delivered his State of the Union address, the memo claimed the alleged affair with Mr Trump “never happened”.

“I am not denying this affair because I was paid ‘hush money’ as has been reported,” the statement read.

“I am denying this affair because it never happened.”

Mr Kimmel asked Ms Daniels to confirm details she provided in a 2011 interview with In Touch magazine, in which she claimed to have had sex with Mr Trump at a 2006 golf tournament about four months after his wife Melania gave birth to their son Barron.

The 38-year-old admitted she hadn’t read the full transcript of the In Touch interview because she was “too scared”.

“Did you do that interview?” Mr Kimmel asked.

“Not as it is written,” Ms Daniels said.

Mr Kimmel then proceeded to recount Ms Daniels’ comments to the magazine: “He told you you should be on The Apprentice. You engaged in textbook generic sex and he did not use protection. Is any of that true?”

“Define true,” said Ms Daniels.

Mr Kimmel asked Ms Daniels whether she had signed a non-disclosure agreement (NDA) about the alleged encounter with Mr Trump.

“If you didn’t have a non-disclosure agreement, you most certainly could say I don’t have a non-disclosure agreement, yes?” Mr Kimmel asked.

“You’re so smart Jimmy,” was Ms Daniels’ response.

US media have speculated that Ms Daniels was attempting to remain in technical compliance with a nondisclosure agreement, while leading the the public to conclude that her denials are not genuine and that the affair was real.

The Washington Post’s Dan Zak reported that Ms Daniels performed at a South Carolina strip club this month that promoted her appearance with the following slogan: “HE SAW HER LIVE. YOU CAN TOO!”

Ms Daniels was scheduled to face a fresh on-air grilling on popular US panel showThe View on Thursday local time, but has cancelled her appearance.

“Stormy Daniels was supposed to be coming on The View and we are not sure that that’s happening anymore,” panelist Whoopee Goldberg said on the show Thursday morning (AEDT).

A spokeswoman for the show confirmed to The Hollywood Reporter that Ms Daniels won’t appear as scheduled, but did not provide a reason for her decision to cancel.

The White House and Mr Trump have never directly addressed the allegations of the affair and cover-up, but Mr Trump’s lawyer has denied the affair.
