Queen Camilla raised eyebrows for her recent interaction with Princess Kate Middleton as the royals met with President Donald Trump and his wife, Melania Trump, in the U.K. Camilla, 77, was caught on video in what appeared to be an awkward exchange with Kate, 43, while greeting Melania, 55, at Windsor Castle on Wednesday, September 17. In footage shared via social media, the Princess of Wales walked over to speak with Melania, who was already engaged in conversation with Camilla. Kate and Melania seemingly shared niceties and smiled at each other before Camilla appeared to shoo her daughter-in-law out of the way. Why Kate Middleton Didn't Curtsy to Donald Trump During State Visit Royal watchers claim that the queen told Kate to "move" and then swept her hand to motion that Kate move along. Kate then walked away toward husband Prince William and Trump, 79, who were speaking with King Charles III.

Other users, however, claimed that Camilla was ushering Kate out of the way because the horse and carriages were arriving and would be stopping close to where she was standing. "It has nothing to do with being shooed away," one viewer commented via X.

The royals and the Trumps can then be seen standing in a line so the horses can approach.
