Camilla Parker Bowles has sepped in for Queen Elizabeth II.

According to New Idea, the Duchess of Cornwall represented the Queen at the London Trump affair. Camilla and Prince Charles met with Melania and Donald Trump ahead of the NATO reception at Buckingham palace.

On Tuesday, the Prince of Wales and Duchess of Cornwall had afternoon tea with the president and first lady of the United States at Clarence House. Camilla was stunning in her full-length white lacy frock with three-quarter sleeves and intricate lace detailing across the bodice and skirt. She kept her makeup simple and wore her tresses in blowout style to the side.

On the other hand, Melania was gorgeous in her flowing red gown that featured a high neckline and billowy cape style sleeves. The FLOTUS also wore a barely-there makeup that showed off her youthful glow. She wore her locks in a side-swept style.

Meanwhile, Prince Charles and Donald were both dapper in their black tuxedos. All of them looked great when they posed for a photo together.

Initially, Donald accused climate experts of having “political agenda.” Prince Charles is known for being an active advocate against climate change and a supporter of sustainability. The U.S. politician listened to the royal and even agreed with his causes.

“What he really feels one way about is the future. He wants to make sure future generations have climate that is good climate as opposed to a disaster, and I agree,” Donald said about his conversation with Prince Charles.

In the evening, Prince Charles, Camilla, Donald and Melania reunited again for a dinner at the palace. They were joined by Queen Elizabeth II and Kate Middleton.

Prince William was noticeably missing because he was in an official tour to Kuwait. Prince Harry and Meghan Markle also did not make it because the couple is still in their six-week vacation.

Prior to Melania and Donald’s arrival in the U.K., the couple was spotted at the White House Lawn. Melania was even photographed smiling and waving at the photographers as she made her way into the helicopter. It was raining and Donald walked ahead but stopped before he reached the helicopter to wait for his wife.
