The Princess of Wales could be set for a reunion with First Lady Jill Biden later this year.
The White House confirmed on Wednesday that the King has invited US President Joe Biden for a state visit.
Spokeswoman press secretary Karine Jean-Pierre said that Mr Biden had accepted the invite during a recent telephone call.
State visits typically involve a review of a military guard of honour and a state banquet, which is usually attended by senior members of the royal family.
The Princess of Wales teamed up with Mrs Biden as they attended the G7 Summit in Cornwall in 2021, when they led a roundtable discussion with experts from the early years sector at a primary school. Take a look at their sweet rapport...
News of the state visit invitation comes after it was confirmed that Mr Biden, 80, would not be attending Charles's coronation on 6 May with Mrs Biden representing the USA.
Ms Jean-Pierre said that Mr Biden had a telephone call of 25 to 30 minutes with the King.
She said: "He congratulated the King on his upcoming coronation, they have a very friendly conversation, he has a good relationship with the King.
"He talked about how he enjoyed visiting the Queen back in 2021 when he and the First Lady came to Windsor and he hoped to visit again soon."

"So they will see each other again very soon, they have a very good relationship, there are many things that they both care about, key shared values, key shared issues, that they want to continue to discuss like climate change.
"And that conversation will continue in the visit in the near future."
She added: "I do not have a timeline, I can't say when it will be but the president was appreciative of the offer by the King and looks forward to it."
A Buckingham Palace spokeswoman told PA News Agency they would not comment on the arrangement.
