She was the ultimate sex symbol as one of the greatest names in golf.

And so it's no surprise former Australian professional golfer and pin-up girl Jan Stephenson caught the attention of a very young Donald Trump about 40 years ago.

The 64-year-old spoke candidly about the moment she dated the up-and-coming billionaire and then ended their relationship to focus on her sporting career.

'He had the whole package,' Stephenson - who is currently travelling around Australia as a music promoter of The Legendary Voices of Rock tour - told Daily Mail Australia.

'Donald was good looking, charming, very accomplished and wealthy and he always had a lot of beautiful women who wanted to go out with him.

'He was not the Donald you see today.'

The pair met in New York in 1976 after she travelled to the States on a business trip - which eventually led to extravagant dinners at fancy restaurants.

'He wrote me a letter to say he wanted me to represent one of his casinos so I flew to New York to meet him,' she said.

'My commissioner asked me "do you know who this Donald Trump is? because he was definitely someone good to meet". He was a big deal in NY and he was certainly big because of his father.

'We kind of started seeing each other. It was all business at first but then he took me to all these beautiful restaurants and we did the whole disco and the whole 70s retro.

'You couldn't really ask for anyone else to spend time with.'

The former No. 1 was the ultimate pin-up girl in the 70s and 80s, who revealed she turned down the billionaire

Stephenson, who graced the covers of sports magazines, revealed how the US presidential candidate opened up to her on what he was looking for in a woman.

'Donald said he wanted someone who is very accomplished and intelligent. He wanted someone who was not just a pretty face but smart and athletic,' she revealed.

'He told me he was seeing another woman - Ivana (former wife) who was a skier - and me at the same time - he was very honest about that. I told him that I wanted to keep our relationship quiet.

'I remember one time he went to watch me play and there was a big media crowd and he ended up signing autographs. He did break my concentration,' she continued as she laughed.

The former athlete said her parents were working several jobs to make ends meet in order to help their daughter pursue her dream as a golfer.

'I had given up so much and my family had given up so much for me to even be here so I didn't want to have a relationship right now, I wanted golf,' she said.

'I came from Australia and my whole life is here. My mum was working two jobs and dad did shift work. I felt like I would be letting everybody down if I gave it all up.'

So the up-and-coming billionaire gave Stephenson the ultimatum to choose between their relationship or her career.

'He was really frustrated with me because I didn't want to give up my career,' she recalled.

With their relationship on the line, Mr Trump chartered a private jet from New York to Atlanta, where Stephenson was scheduled to play in a tournament the following day.

'He asked if I wanted to have dinner with him but I told him I was playing a tournament so he sent a plane to an airport nearby,' Stephenson said.

'So I drove out to the plane and when the door came down, Donald didn't come out and the pilot told me to come up. When I stepped in, the plane was full of red roses - it was beautiful.

'And there was one rose and an invitation sitting on a seat. I opened it and there was the name of a restaurant I had never heard of.

'So I turned to the pilot and asked "where is this restaurant?" and he said "it's in Paris".

'I thought "well I can't do that, I've got to play in my tournament tomorrow" so I actually said "thanks but no thanks". I didn't hear back from him for a while.'

Just a few years ago, the former No.1 golfer said Mr Trump got back in touch with her to line up a match between his banker and Stephenson.

'Donald asked me to play with one of his bankers and when I arrived, he [banker] said "I heard you could've been the next Mrs Trump",' she said as she laughed.

'But Donald did asked me if I regretted that decision but I said I didn't.

'My goal was to play golf and I couldn't just take 10 years off - especially in sport - to be in a relationship. It doesn't work that way. I had my goal and I made them and it was wonderful.'

Stephenson went on to win three major championships, while Mr Trump became a property mogul, reality television star and an aspirant Republican presidential.

And 40 years on, Stephenson admits she does wonder what could have happened if their relationship continued on.

'I do wonder what my life would've been or what could've happened if I did stay around,' she said.

'When I look back, the only regret I have is it was just one tournament so I could've gone to dinner. Even my commissioner at the time said I should go for it but I chose my career instead.

'He was pretty upset at the time. It was a beautiful and romantic gesture. He was very thoughtful and definitely a fantastic family man. We have stayed as pretty good friends though.'
