President Donald Trump and First Lady Melania Trump returned to Buckingham Palace on Tuesday night for a NATO anniversary reception hosted by Queen Elizabeth.
They were last at the palace in June, for the president's state visit to the U.K., when he was joined by all of his adult children: Donald Trump Jr., Eric Trump, Ivanka Trump (a senior White House aide) and Tiffany Trump.
But unlike that outing, none of his kids made the trip this week, where the president's schedule is largely full of meetings with other NATO leaders.
Before Tuesday's reception, he and the first lady had tea with Prince Charles and Camilla, Duchess of Cornwall, who were also on hand for the Buckingham event along with Kate Middleton.
The Trumps will head to another reception Tuesday night hosted by Boris Johnson, the U.K.'s prime minister. They are due back in the U.S. on Thursday.
This week's visit, as with previous Trump trips across the Atlantic, has been met with protests.
