A former supermodel said Donald Trump's 'vulgar' and 'sexist' remarks about the size of women's breasts forced her to switch tables at a White House dinner party.

Sports Illustrated cover model Vendela Kirsebom claims her night at the 1993 Vanity Fair event was ruined because she was sat next to billionaire Mr Trump.

Recalling the 'excruciating' night, Ms Kirsebom, 49, told MailOnline: 'Everything he said was so vulgar. I couldn't listen to his nonsense for an entire night so I asked if I could be moved.

'He talked about big breasts, small breasts, how one was better than the other and the differences between them.

'He talked about big breasts, small breasts, how one was better than the other and the differences between them,' Ms Kirsebom said of Mr Trump, whose election campaign has been hit by claims of sexism. Pictured: Melania Trump and her husband Donald at the 2016 Time 100 Gala in April

'His main focus was breasts and the sizes of women's bodies. Fat women were not real women in his opinion.'

She added: 'He basically said if you are not attractive and beautiful, then you don't have any purpose as a woman.'

Ms Kirsebom, who speaks six languages, is a mother of two daughters who was married for 11 years to Norwegian politician Olaf Thommessen.

She told MailOnline Trump as president 'would be awful for the entire world'.

Vanity Fair editor-in-chief Graydon Carter, who organised seating for the event, wrote he sat Ms Kirsebom next to Mr Trump because he thought 'she would get a kick out of him'.

He added: 'After 45 minutes she came over to my table, almost in tears, and pleaded with me to move her.

'It seems that Trump had spent his entire time with her assaying the "t***" and legs of the other female guests and asking how they measured up to those of other women.

'"He is," she told me, in words that seemed familiar, "the most vulgar man I have ever met."'

Ms Kirsebom told MailOnline she was close to tears as the Republican presidential candidate, 70, also spent the evening belittling his then-fiancee Marla Maples.

'The night was suppose to be about politics and meeting interesting people, not sitting next to someone who degraded the women he saw,' she said.

'I was really p***** off and mad at the time. The whole experience was really too much.'

Mr Trump's chances of winning the US presidential election were dealt a severe blow last week when a video emerged of him describing in lewd terms how he had groped and tried to have sex with a married woman.

On the tape, from 2005, Mr Trump appeared to suggest that he had used his powerful position to make sexual advances on women.

In the recording, Mr Trump says of the unknown woman: 'She was married. I moved on her very heavily. When you're a star they let you do it. Grab them by the p**** ... you can do anything.'

Trump was filmed arriving on the set of a daytime soap opera, Days of Our Lives, for the recording of a segment in which he was to have a cameo, the Washington Post, who obtained the video, said.

He was speaking to Billy Bush, host of Access Hollywood, a programme about celebrities, as they arrived on board a bus with the show's name written on the side.

The property magnate apologised in a statement: 'This was locker room banter, a private conversation that took place many years ago. Bill Clinton has said far worse to me on the golf course — not even close. I apologise if anyone was offended.'

She said she was close to tears when she eventually pleaded to change seats, so she could enjoy the rest of the night in peace. Pictured: Ms Kirsebom modelling in 2001

And on Thursday BuzzFeed News reported Mr Trump had walked into the dressing room at the 1997 Miss Teen USA where contestants as young as 15 were changing.

Four women reportedly claimed that he entered their dressing room - an intrusion they reportedly found 'shocking' and 'absolutely inappropriate'.

But in a statement to Us Weekly, Mr Trump's campaign Deputy Communications Director, Jessica Ditto, denied the allegations.

'These accusations have no merit and have already been disproven by many other individuals who were present.

'When you see questionable attacks like this magically put out there in the final month of a presidential campaign, you have to ask yourself what the political motivations really are and why the media is pushing it. Here's the reality – Mr. Trump has a fantastic record of empowering women throughout his career, and a more accurate story would be to show how he's been a positive influence in the lives of so many.'

In 1996, he was accused of bullying former Miss Universe Alicia Machado when she put on weight after the competition - branding her 'Miss Piggy' and inviting the press to watch her work out.

None of it comes as a surprise to Ms Kirsebom who claims 'he has not changed a bit' since their encounter 23 years ago.

She said: 'I met him on numerous occasions after that [White House] dinner since we shared the same press agent. He was always himself and I felt he was a chauvinist most of the time.

'He did not say much about Bill or Hillary Clinton. But I thought that he was a supportive Democrat at the time.

Mr Trump was already playing catch up to Clinton after a CNN poll, taken after his disastrous first debate with the Secretary of State, put him trailing by 14 points among women.

Several top Republicans, including House Speaker Paul Ryan, have deserted the reality TV star since the 'p****gate' video emerged.

More than 20 Republican senators, governors and representatives rescinded their support for Trump since Jason Chaffetz of Utah declared, 'I'm out', on Friday night, according to the Huffington Post.

MailOnline has contacted Donald Trump for a comment.
