Miss Laaksonen said she also attended some house parties with the other contestants and Mr Trump’s wife, Melania, who he had married the year before.
“Somebody told me there that Trump liked me because I looked like Melania when she was younger,” she said.
“It left me disgusted.”
Trump has denied all the allegations, saying that he will sue all his accusers.
“The stories are all totally false,” he told Good Morning America on Thursday morning.
His wife, Melania, also denied the flood of accusations.
“They are lies,” she said.
“And as I’ve said before, the accusations should be handled in a court of law. Because to accuse somebody without evidence, it’s very hurtful and very unfair.
“But honestly – do we need to talk about that? The American people want to hear about the issues.”
