Joe Biden has said the Queen reminds him of his own mother after Her Majesty hosted and POTUS and FLOTUS over the weekend.
The incumbent president, 78, and The Queen, 95, interacted at the G7 summit in Newquay, Cornwall on Friday, before taking tea together on Sunday.

Mr. Biden and First Lady Jill Biden were welcomed at Windsor Castle in Berkshire at around 5 PM.
After spending some time with the British royal, the Democratic president told reporters, per The Sun: "I don't think she’d be insulted but she reminded me of my mother, the look of her and just the generosity."

He went on to say that Her Majesty had enquired about the President of China Xi Jinping and Russian President Vladimir Putin, who Biden will be meeting later this week.
"She wanted to know what the two leaders that I - the one I'm about to meet with, Mr. Putin, and she wanted to know about Xi Jinping," the president said, according to the outlet.
He added: "I said I wish we could stay longer, maybe we could hold the cars up a minute, and stuff. Anyway, she was very gracious."
Biden also told the reporters that he had invited the Queen to the White House.
"She said, 'What's it like in the White House?' I said, 'Well it's magnificent but it's a lot of people,'" he continued.
At the reception for G7 Summit, which took place in Cornwall's The Eden Project, the Bidens were seen laughing as the Queen joked: "Are you supposed to be looking as if you're enjoying yourself?" while they posed for a photograph.
The Queen, who has been on the throne for 69 years, has met all but one of the 14 US presidents elected in that time. The president she did not meet was Lyndon Johnson, who was in office from 1963 to 1969.
In 2018, she hosted an afternoon tea for President Trump and his wife Melania at Windsor Castle. She first met Barack Obama and then-First Lady Michelle Obama during the couple's visit to Buckingham Palace in 2009.
