When the world’s most powerful man, US President Donald Trump found himself in a battle with a porn star, not even he could have predicted where that would lead.

Thirty-nine-year-old Stormy Daniels alleges she and the now-president had a sexual encounter when he was a television celebrity and host of The Celebrity Apprentice.

‘Stormy Daniels’ airs 8.30 tonight on Channel 9 after The Block. For more on 60 Minutes, head to the official website .

“I’m not a liar. And I am not a gold digger,” Daniels tells Hayes. (60 Minutes)

Trump denies the allegation, calling it more fake news.

But since making her claims, Daniels has not taken a step back.

And tonight, in an exclusive Australian 60 Minutes interview, she tells her story in all its extraordinary detail.

Reporter Liz Hayes met with Daniels at an isolated property in America, a place where Daniels says she feels most at home.

“Stormy left nothing to the imagination,” says Hayes.

“But what this is really about is truth and lies.

“If Donald Trump hadn’t declared her a liar, this is a story that would have died a long time ago.”

It started back in 2006, when Daniels claims she met Trump at a celebrity golf tournament at Lake Tahoe.

Trump claims Daniels invited her to his penthouse.

She says she expected they would be having dinner, but instead, she alleges she left hungry after what she describes as “the least impressive sex she’s ever had”.

According to Daniels, she’s rejected an offer to settle further legal disputes. (60 Minutes)

Daniels claims they maintained contact for the next 18 months.

When the relationship fizzled she says she forgot about it, until a story appeared on a gossip website, five years later.

In 2016, when Trump was campaigning for the presidency, Daniels was approached to sign a $130,000 non-disclosure agreement.

Then this year, she claims, she was approached again to sign a second agreement to make public a statement, that she did not have sex with the now-president.

Daniels decided she’d had enough, but what followed she says, has been traumatic and scary.

“Daniels says she’s had hundreds of death threats. She has body guards and takes special precautions to ensure her seven-year-old daughter’s safety,” says Hayes.

“She was arrested by vice cops at a strip club in Ohio after one of her shows.

“That arrest is now being investigated by the FBI.”

Michael Cohen has recently pleaded guilty to eight charges including campaign finance fraud stemming from hush money payments to Stormy Daniels and another woman, ex-Playboy model Karen McDougal, who is also alleged to have had an affair with Trump.

And according to Daniels, she’s rejected an offer to settle further legal disputes.

“I’m not a liar. And I am not a gold digger,” she tells Hayes.
