However, reporters at the event told a different side of the story, with many of them pointing out that Anne was likely not in the receiving line to greet the president and first lady because she is not the heir to the throne like her brother, Charles.
In an article for Belfast Telegraph, Laura Elston wrote that the actual interaction between the queen and Anne began when the monarch turned to see which world leader she'd meet next and instead saw her daughter standing in the doorway.
According to the outlet, Anne raised both her hands in the air, laughed and remarked, "It's just me," before adding "and this lot" in reference to members of the household behind her.
At the reception itself, however, Anne was seen speaking with Canada's Justin Trudeau, France's Emmanuel Macron, Britain's Boris Johnson and others as they appeared to speak ill of Trump.
If you ever wondered what world leaders chat about in private, well here at NATO they’re gossiping about #Trump.
