Middleton agreed with a smile and a slight nod and the throngs of onlookers erupted in cheers as the two kissed again.
After the kiss, Middleton blushed and began laughing at the crowd's ecstatic reaction while William grinned and continued waving.
The sweet moment was viewed by millions of fans all over the world and widely covered in the media
William's parents, King Charles III and the late Princess Diana, were the first royal couple to kiss on the iconic balcony after tying the knot in July 1981. The unprecedented move reportedly broke with royal etiquette but started a new tradition, which has been carried on in the years that followed.

Charles' younger brother Prince Andrew shared a kiss on the balcony with his bride Sarah Ferguson, the Duchess of York, after they married in July 1986.
Though William's younger brother Prince Harry and his wife Meghan Markle didn't kiss on the balcony after their May 2018 wedding, the pair locked lips on the steps of St. George’s Chapel shortly after exchanging vows at Windsor Castle.

While William and Kate previously tended to keep their PDA to a minimum, the two have openly shared several affectionate moments over the past year.
In July, the pair embraced and kissed each other on the cheek at the Royal Charity Polo Day. William, who competed in the charity polo match, was also spotted with his arm around his wife's back.

Still, the couple tend to err on the side of propriety while out in public or conducting their royal duties. Meier told the outlet that senior royals would use their judgment as far as public affection.
"The royals often adjust PDA to mirror the formality of the event they are attending. At a somber or more formal event, we are less likely to see PDA than at a casual event where it would be deemed more fitting," she said.
