Donald Trump says he is not aware of an invitation for him to attend the wedding of Prince Harry and Meghan Markle.
When asked in an interview with Piers Morgan about whether he has received an invite, the US president replied: "Not that I know of."
Ms Markle has been a vocal critic of Mr Trump and backed his rival Hillary Clinton, saying she would leave the US if he won the 2016 election.
When asked if he would like to go to the Royal wedding in May at Windsor Castle's St George's Chapel, Mr Trump would only say: "I want them to be happy. I really want them to be happy. They look like a lovely couple."
When Morgan said Ms Markle had called him "divisive" and a "misogynist", Mr Trump responded: "Well, I still hope they're happy."
On Brexit, the President said he was unsurprised by the result of the referendum because Britons "don't want people coming from all over the world into Britain" and claimed the European Union was "not cracked up to what it's supposed to be".
He also said he would have negotiated Brexit with a "different" and "tougher" attitude to Theresa May.
"Would it be the way I negotiate? No, I wouldn't negotiate it the way it's (being) negotiated… I would have had a different
attitude," he said.
"I would have taken a tougher stand in getting out."
Mr Trump also claimed Mrs May invited him to the UK twice this year during their meeting at the World Economic Forum in Davos, Switzerland.
But Downing Street did not confirm the newspaper's claim that an informal visit in July would be followed by a state visit in October.
A Number 10 source said: "An invitation has been extended and accepted and details will be set out in due course."
The President also suggested that the US could come back in from the cold after opting out of the Paris Accord on climate change.
The decision triggered scorn from the international community and "disappointment" from Mrs May.
"The Paris Accord, for us, would have been a disaster. I'm completely out of it," he said.
"First of all, it was a terrible deal for the United States. If they made a good deal… there's always a chance we'd get back.
"Would I go back in? Yeah, I'd go back in. I like, as you know, I like Emmanuel (Macron, French president). I would love to, but it's got to be a good deal for the United States."
Asked about his constant use of Twitter, Mr Trump said he sends the tweets himself but will delegate if he is busy.
He said: "Well, perhaps sometimes in bed, and perhaps sometimes at breakfast or lunch, or whatever.
"But generally speaking, during the early morning or during the evening, I can do that.
