According to a new book, Queen Elizabeth II had harsh words for former President Donald Trump’s manners, the Daily Mail reports.

In his forthcoming book Q: A Voyage Around the Queen, scheduled for publication in the U.S. by Farrar, Straus and Giroux on Oct. 1, author Craig Brown writes that the late monarch was unimpressed with the bombastic president after he visited her in England.

“'A few weeks after President Trump's visit, for instance, she confided in one lunch guest that she found him ‘very rude’: she particularly disliked the way he couldn't stop looking over her shoulder, as though in search of others more interesting,” Brown writes.

The queen was so appalled by Trump’s manners, Brown writes, that she questioned his wife Melania Trump’s motivations in marrying him.

“She also believed President Trump ‘must have some sort of arrangement’ with his wife Melania, or else why would she have remained married to him?” Brown writes.

Trump was asked about Brown’s claims, and dismissed them.

“It was totally false,” he told a reporter. “I have no idea who the writer is, but it was really just the opposite. I had a great relationship with the queen; she liked me and I liked her. I spoke to her often, and I spoke to her in particular when I was there. We spent hours together at a state dinner. She was a fantastic woman. I think it’s a shame that a sleazebag can write an article that’s totally false. In fact, I’ve heard always the opposite. I heard I was her favorite president, and you’ve heard that too. She would say that to a lot of people.”
