Stormy Daniels let a pal listen in when Donald Trump would call her more than a decade ago — and the friend has since confirmed that the porn princess had a fling with the future president.

Keith Munyan, a photographer who is one of the four people listed as knowing about the alleged relationship in a non-disclosure statement Daniels signed to keep quiet about the 2006 tryst, said the future president was always polite when he called.

“The only thing I ever heard him do is just babble like he always does,” Munyan told The Washington Post.

Daniels’ lawyer, Michael Avenatti, on Monday proposed a deal with Trump’s personal lawyer Michael Cohen in which Daniels — whose real name is Stephanie Clifford — would repay the $130,000 in hush money she got for signing the agreement if Team Trump would stop trying to keep her quiet.

Avenatti set a deadline of noon Tuesday for a response — but heard only crickets as the deadline passed.

“The President and Mr. Cohen have purposely ignored our settlement offer, thus doubling down on their efforts to muzzle Ms. Clifford and prevent her from telling the American people what happened. Time to buckle up. #basta,” he wrote on Twitter — the Spanish and Italian word for “enough.”

Trump through his spokeswoman has denied the affair — which allegedly took place as his third wife, Melania, was at home caring for their then-infant son Barron — though the president himself has not publicly commented.

Daniels has been interviewed by CBS’ “60 Minutes,” which has not set a date for the segment to run.

Meanwhile, the president has been speaking with friends about how best to handle the tawdry allegation, CNN reported.

A source told the network that Trump was told by advisers not to fight Daniels’ decision to break a confidentiality agreement because it would make him look guilty — and that that’s the only reason he had so far stayed quiet on the issue and hadn’t tweeted about it.
