Ms Daniels signed her copy on the trunk of a car near a porn set in California. Mr Cohen signed on Mr Trump’s behalf.
After some delay, Mr Cohen eventually used his own money to pay her, an act that would later land him in jail.
But Mr Trump is alleged to have both instructed the payoff and signed checks to reimburse Mr Cohen after he was in the White House.
In the end, the money was wasted.
The story came out anyway two years later in 2018 when Ms Daniels sued Mr Trump in an attempt to overturn the NDA and In Touch Weekly published the kiss-and-tell article.
Reality star
Since then, the porn actress has not shied away from capitalising on the publicity.
She launched a perfume called Truth with the tagline: «It’s the bomb! Sensual living. Stormy Daniels Embrace your Truth.»
In July 2018, she was arrested by undercover police officers during an undercover vice operation at a strip club in Columbus, Ohio.
She was accused of illegally touching a guest at Sirens Gentlemen’s Club.
Michael Avenatti, her lawyer at the time, described the charges – which were dropped the following day – as politically motivated.
Ms Daniels had the last laugh, agreeing to a $450,000 settlement with the city.
Her memoir, Full Disclosure, written with journalist Kevin Carr O’Leary, was published a month later.
One reviewer described the book as «more flashy than thoughtful» but it contained enough salacious detail to satisfy her readers.
