The Queen, 78, and her husband King Charles III, 77, are spending four days across the pond with US President Donald Trump and the First Lady, attending events fit for royalty and partaking in a number of engagements. 

On Tuesday (28 April), the second day of their visit, the couple's agenda was jam-packed, with Charles making history with his speech to US Congress, followed by a lavish state banquet. 

But the day also included a ceremonial arrival to the White House, where they were greeted by Trump and Melania on the South Lawn, where four chairs were set up for them. One clip doing the rounds on social media shows the two ladies, both wearing all white, sitting down and whispering to each other ahead of the president's address.

According to lip reader Nicola Hickling, who spoke to the Daily Mail, Melania was left confused by a particular two-word phrase used by the Queen. 

The expert, who analysed the clip, believes that the Queen remarked: "Oh, it's rather wet," to which Melania laughed: "It certainly is." Camilla reportedly responded with: "We shall have soggy bottoms," which Melania apparently seemed to question what she'd said, enquiring: "Soggy bottom." This makes sense since it is a very British phrase. 

It was popularised on The Great British Bake Off to describe an undercooked, wet, or pastry base on pies, tarts, or other baked goods. 'Bottom' also isn't as commonly used for those in the US to describe, ahem, someone's behind, as they usually opt for 'butt'. On Tuesday, as mentioned, the King also delivered a historic speech to the US Congress.

In 1991, the former Queen - who passed away in September 2022, aged 96 - delivered a speech to Congress which lasted 12 minutes. 

The King said: "Distinguished members of the 119th Congress, it is here in these very halls that this spirit of liberty and the promise of America’s Founders is present in every session and every vote cast. "Not by the will of one, but by the deliberation of many, representing the living mosaic of the United States. 

"In both of our countries, it is the very fact of our vibrant, diverse and free societies that gives us our collective strength, including to support victims of some of the ills that, so tragically, exist in both our societies today."
