The video shows Prince Charles' wife, 71, winking after she and her husband teamed up with the US president and First Lady Melania Trump for a photo during tea on Monday at their residence, Clarence House.
PEOPLE reported that Camilla was sharing a fun moment with a member of the staff.
“Camilla’s wink is probably the best thing about this visit so far,” one user tweeted on Monday along with a GIF of the wink.
Scott Dworkin, a Trump critic, wrote: “Camilla’s wink is all sane people on earth.”
Another user wrote: “And with that one wink, Camilla’s approval rating [triples].”
Despite large protests, Trump made his 3-day visit to the UK.
“This state visit will reaffirm the steadfast and special relationship between the United States and the United Kingdom,” the White House said in a statement.
In a tweet, the palace confirmed: “the President of The United States of America, President Donald J. Trump, accompanied by Mrs Melania Trump, has accepted an invitation from Her Majesty The Queen to pay a State Visit to the UK.”
