Princess Kate gave her first curtsey to her father-in-law King Charles in a mark of respect to the newly crowned monarch.
The stunning moment was captured as he walked down the aisle at Westminster Abbey wearing St Edward's Crown.
It will be the only time in his life that Charles will wear the 360-year-old crown, which is made of solid 22-carat gold.

Sophie, Duchess of Edinburgh followed after the Princess of Wales with a curtsey as the King, her brother-in-law, passed her.
The act of a curtsey is a traditional sign of deep respect when greeting a monarch.
Women typically greet the sovereign with a curtsy and small bow of the head if they are seeing them for the first time that day.
While for men the greeting is typically a head bow.
During the ceremony, The Princess of Wales stunned in a three-dimensional leaf embroidery headpiece by milliner Jess Collett and Alexander McQueen.
She wore regal robes at the coronation, including a deep blue Royal Victorian Order mantle edged in scarlet over an Alexander McQueen embroidered ivory silk crepe dress.
Kate also paid homage to Princess Diana by wearing a pair of earrings Diana wore in 1990.
And in honour of the late Queen Elizabeth II, she wore the George VI Festoon Necklace — a gift from King George VI to his daughter, then Princess Elizabeth.

Throughout her reign, Queen Elizabeth II was spotted wearing the George VI necklace on several significant occasions — including the State Opening of Parliament in 2012 and a State Banquet at Buckingham Palace in 2018.
Princess Charlotte was dressed in a mini-me version of her mother, with a similar crystal headpiece by the same milliner.
Eight-year-old Charlotte also wore an Alexander McQueen dress – with a cape – in ivory silk crepe.
