US President Donald Trump and First Lady Melania Trump were invited by King Charles to visit Britain, which marked their second visit of the country.

Upon touching the British soil, the couple were greeted by The Prince and Princess of Wales before meeting the king and the queen.

The visit was marked by a number of noteworthy moments, among them Camilla’s side-eye at Kate joining her conversation with Melania, and the king cracking a joke with Melania that many found rather amusing.

Truth is, many are aware of the humorous side of King Charles, and him making a witty comment upon greeting Melania became a much-discussed topic in the last couple of days.

According to forensic lipreader Nicola Hickling, who spoke to Metro, Donald Trump opened with a formal greeting—“How are you doing, it’s a pleasure, Your Majesty. Thank you for inviting me.” King Charles then turned to the first lady and said jokingly, “I do hope the wind doesn’t blow away your hat.”

Melania’s response was a genuine, hearty laugh.

The first lady’s fashion statements have always been bold, and they often incorporated hats — which she clearly loves.

She wore a similar black hat at her husband’s Inauguration Day in January, and just like at that point, this time, her hat sparked debate.
