Prince William’s 6-word joke about Donald Trump during state visit 'revealed' by lip reader

A lip reader has revealed a sweet six-word joke Prince William made about Donald Trump as they greeted the US president.

Trump is currently on his second state visit to the UK, which is unprecedented for a US president, as most only visit once.

The US president and his wife Melania were greeted by Prince William and Princess Kate Middleton as the presidential helicopter touched down at Windsor Castle.

As the royals met the president and Melania, the four then walked across the lawn together towards the castle, talking as they went.

Now, a lip reader has revealed what they may have been saying to each other as they walked across.

Speaking to The Sun, the lip reader said that the president opened the conversation by greeting William, saying: "Hello my friend, how are ya?" before turning to Kate and saying: "Hello, beautiful, beautiful."

Melania then spoke up, greeting Prince William by telling him: "It’s a pleasure to see you."

She then turned to Kate and said: “How are you?”

Inviting them to the castle, William then placed his hand on Kate's back and said: "Let’s walk over together."

Trump nodded in agreement, and they set off across the lawn, Trump and William in the middle, flanked by Kate and Melania.

As they walked, Trump asked William about George, Charlotte, and Louis, saying: “How are the children?”

The heir to the throne replied: "They're well and at school."

If the lip reader is correct, Trump appears surprised by this, saying: "Well, blow me."

The Prince of Wales added: "The new term started a couple of weeks ago."

Trump then said: "It’s been a while since you chatted with me."

At this point, William appeared to share a sweet joke with Kate, telling her: “He has missed our little chats.”

He then turned back to Trump, saying: “We can talk now you’re here on a visit.”

Trump gave a slightly cryptic reply, saying: "We have lots to catch up with, and there’s been lots of changes.”

The state visit will see Trump and his entourage staying in the UK for two days, with most of the events being held behind closed doors in a bid to avoid protesters unhappy with Trump's presence in the UK.

Controversy has already clouded the visit as police arrested four people after an image of Donald Trump with convicted paedophile Jeffrey Epstein was projected onto the side of Windsor Castle.
