An awkward moment between Queen Camilla and Kate Middleton was caught by cameras during their formal state visit welcome with First Lady Melania Trump.

The Princess of Wales, 43, was locked deep in conversation with President Donald Trump’s wife, 55, when the Queen, 78, appeared to instruct Middleton to move along, to which she obliged.

In the video, taken on Wednesday, Sept. 17, Trump and his wife were greeted by Prince William and Middleton on the grounds of Windsor Castle to begin their days-long visit to the UK.

Following the initial greeting, William and Middleton took the Trumps to meet with King Charles and Queen Camilla outside Victoria House.

The monarch greeted Trump and the first lady with kindness, as did their private secretaries, Sir Clive Alderton and Sophie Densham, before the conversations broke off.

President Trump began speaking to King Charles and Prince William while Camilla turned to Melania and started to chat.

Middleton then came over to her mother-in-law and started engaging in conversation with the first lady. Queen Camilla looked uncomfortable, awkwardly looking around as Middleton and Melania spoke.

A few short moments into their discussion, the Queen seemingly motioned Princess Kate to move along with a casual sweep of her hand.

Middleton got the message loud and clear.

She quickly wrapped up her conversation with Melania and walked back toward her husband’s side, leaving Queen Camilla to have a private discussion with the first lady as the group cleared a path for horse-drawn carriages to take them away to Windsor Castle.
