Donald Trump has boasted that he had "automatic chemistry" with the Queen during his state visit to the UK this week.
The US president praised the monarch as a "spectacular woman" but said he did not fist-bump her when he arrived at Buckingham Palace.
In an interview with Fox News broadcast on Thursday, Mr Trump also said people had noticed how well he and the Queen had connected.
He added: "The meeting with the Queen was incredible, I think I can say I really got to know her because I sat with her many times and we had automatic chemistry, you will understand that feeling.
"It's a good feeling. But she's a spectacular woman."
Mr Trump, when asked by Fox News' Laura Ingraham if he fist-bumped Her Majesty, said: "I did not, but I had a great relationship, we had a really great time.
"There are those that say they have never seen the Queen have a better time, a more animated time.
"We had a period we were talking solid straight, I didn't even know who the other people at the table were, never spoke to them. We just had a great time together."
Mr Trump was asked if he would keep the conversation going and added: "Yes I am, she is a spectacular woman, an incredible woman."
The president was given a ceremonial welcome and a grand state banquet at Buckingham Palace during his visit to London.
He also sat next to the Queen to observe the 75th anniversary D-Day commemorations in Portsmouth on Wednesday.
