The Princess of Wales issued a concerned four-word warning to Prince William ahead of the Coronation, according to a lip reader.
The couple arrived at Westminster Abbey with their children Princess Charlotte and Prince Louis and joined the procession before King Charles and Queen Camilla’s crowning report the Mirror.
Both wore formal robes with Kate in her striking Royal Victorian Order mantle, while William sported his Order of the Garter mantle.
Cameras captured the moment the couple lined up waiting for the procession to start, with William and Kate seen exchanging words with each other.
And it appears that the princess had a word of concern for her husband before they started the long walk into the Abbey.
Professional lip reader Jeremy Freeman told the Daily Star Kate turned to William and said “just mind the gown”.
And he believes the heir to the throne replied with reassurance saying: “Don’t worry I got [or caught] it.”
Thankfully, it appeared there were no hiccups with the robes during the procession or the rest of the Coronation ceremony.
However, one mysterious detail on Kate’s outfit sent royal fans into a frenzy when the official Coronation photos were released.
Her robe largely covered her stunning Alexander McQueen dress but ditched the mantle for the official photos.
However, eagle-eyed royal fans noticed that the V-shaped neckline of the dress in the official photo was seemingly different to when Kate was at the Abbey when it appeared to be a round neck.
It led to speculation online that the princess may have even had two dresses made – despite the embroidery on the skirt remaining the same.
However, the mystery of the neckline of the dress has appeared to have been explained – and it seems it could have all been down to a separate garment.

According to Alastair Bruce, the Sky News commentator and royal expert, Kate wore an additional cape over the top of the dress in order to protect it from the heavy mantle and chains she was required to wear over the top.
It then appears that for the official Coronation photos, Kate removed the cape, revealing the intricate V-shaped neckline, which showed off the stunning George VI Festoon necklace, which was a gift to the late Queen Elizabeth in 1950.
The McQueen dress was created from ivory silk crepe with silver bullion and threadwork embroidery featuring rose, thistle, daffodil and shamrock motifs, representing the four nations.
Her look was completed with a Jess Collett x Alexander McQueen headpiece with silver bullion, crystal and silver threadwork three-dimensional leaf embroidery.
