Unlike other royal weddings, the day will not be broadcast on BBC, with ITV's This Morning instead taking over the coverage.
Princess Eugenie, William and Harry's cousin, is getting married tomorrow to her fiance Jack Brooksbank in the United Kingdom, in fact, right in the same place where Harry's wedding was just a few months ago.
The bad blood is believed to boil over at Princess Eugenie's October 12 wedding to Jack Brooksbank.
Samantha was later photographed holding masks of Meghan and Harry's faces, which she repeatedly purchased at a souvenir stand.
Like Harry and Meghan, the couple will also say their vows in St. George's Chapel, a masterpiece of the "perpendicular Gothic" style with royal connections dating back to 1475, when construction began under King Edward IV.
According to Vanity Fair, Eugenie and Jack have asked guests not to tweet or post pictures on social media, and all guests have been formally advised that they will be asked "to surrender mobile telephones, cameras, and any electronic devices used for image capture" on arrival at the reception. Dooley said he "didn't watch the royal wedding", though he admitted being in London during the nuptials (the actual wedding took place in Windsor).
The Princess of York's ring is a large pink padparadscha sapphire surrounded by 10 perfectly cut diamonds with two cut diamonds at the shoulders, while the Duchess of Cambridge's ring has a large royal blue sapphire, which is also surrounded by diamonds, Mirror News reports.
Eugenie's sister, Princess Beatrice, is maid of honour.
The luncheon with the queen is expected to be a quiet, muted affair - reflecting the 92-year-old monarch's advanced years - with the nighttime shindig seen as a chance for the younger generations to step out in style.
About 38,000 people signed a petition, organised by campaign group Republic, against taxpayers' money being spent on the occasion.
Will Calvert told Sky News this wedding does feel different.
Art-loving Eugenie (pronounced YOO-juh-nee, not you-JAY-nee, but she's said she's "used to every pronunciation") is the Queen's granddaughter and is ninth in line to the throne.
Meghan and Harry obviously have a busy few months ahead.
