On Monday, Kensington Palace took to Instagram to share throwback photos from the Duke and Duchess of Cambridge's 2011 nuptials at Westminster Abbey in London.
The pics show off Kate in her stunning Alexander McQueen gown -- which is believed to have cost $434,000 -- that featured intricate floral needlework, layers of silk tulle and a nine-foot train. Kate also opted for a Cartier halo tiara, which was loaned to her by Queen Elizabeth II. The stunning images also show William in his bright red Irish Guards uniform, with a then-single Prince Harry by his side.
"Eight years ago today -- thank you for your lovely messages on The Duke and Duchess of Cambridge’s wedding anniversary!" Kensington Royal captioned the pics, which also included Kate and William waving to their more than one million well wishers.
The Duke and Duchess' star-studded nuptials were attended by 1,900 guests, including celebrities David and Victoria Beckham, Sir Elton John, Joss Stone and Guy Ritchie. Following the ceremony and their sweet kiss on the balcony of Buckingham Palace, the reception featured an eight-tier traditional fruit cake with white icing and sugar flowers.
Since their wedding day, the couple has welcomed three children, Prince George, 5, Princess Charlotte, 3, and Prince Louis, who celebrated his first birthday earlier this month.
It seems Harry's older brother is eagerly awaiting the birth of his first niece or nephew like the rest of the royal fans! During a recent visit to New Zealand, The Duke of Cambridge joked that he has "no idea" when Baby Sussex will be born.
"You guys will find out before I do at this rate!" William quipped.
