A shocking 1997 Howard Stern interview has re-surfaced in which Donald Trump makes salacious remarks about late Princess Diana and her sexual health.

The president said in two different chats with shock jock Stern he would have slept with the royal beauty, but that he would have made her take a HIV test beforehand.

In an interview with Stern on his morning radio show in 2000, Trump revealed 'without hesitation' he would have gotten intimate with Her Royal Highness - and previously in 1997, he spoke on the topic again.

Trump stated he would have 'nailed' Diana but suggested only under circumstances her HIV test came back clean.

The old remarks re-emerged just days before the Princess of Wales' son, Prince Harry, is set to marry California actress Meghan Markle.

Donald and Melania won't attend the royal wedding - like other political leaders they weren't invited to the society event - but the White House said they will make a donation to one of the charities Harry and Meghan recommended to their guests.   

The couple has asked guests and well-wishers donate to charity close to their hearts rather than buying a gift when they tie the knot on May 19. 

Causes they selected include social change, women's empowerment, conservation, the environment, homelessness and the Armed Forces.

They showed their determination to continue Princess Diana's work in support of people with HIV by nominating the Children's HIV Association, as well.

Stern asked Trump: 'Why do people think it's egotistical of you to say you could've gotten with Lady Di? You could've gotten her, right? You could've nailed her?'

Trump replied: 'I think I could have.'

In a conversation just months after her death, Stern started to imagine a conversation between Trump and Diana, saying: 'Hey Lady Di, would you go to the doctor?' Stern mockingly asks.

Trump then runs with the joke, imagining the conversation with the royal. 

'Go back over to my Lexus, because I have a new doctor,' he says, as if addressing her. 'We wanna give you a little checkup.'

The pair were carrying on an earlier joke in the conversation where Trump said he always made sure women had HIV tests before sleeping with him.

The now president Trump also commented on Diana's appearance in interview.
