This is because she and her now-husband Thomas Kingston decided to have their special day on May 18, 2019, one day before Meghan and Harry's ceremony the year before. Not only this, but they chose the exact same location for their nuptials ‒ St George's Chapel, Windsor Castle. This is also the venue chosen by Princess Eugenie and Jack Brooksbank in October 2018.
Gabriella reportedly chose St George's Chapel because she has "fond memories" of spending Christmas there and being a bridesmaid for Lady Helen Taylor, the daughter of the Duke and Duchess of Kent.
Gabriella's wedding had a private ceremony for the family, followed by a reception at Frogmore House.
Frogmore House is also where Harry and Meghan had their evening post-wedding celebration, and it is a short way away from their old residence, Frogmore Cottage.
However, Gabriella's wedding did not attract nearly as much attention as Meghan and Harry's.
As the daughter of Prince Michael of Kent, the Queen's cousin, and the controversial Princess Michael of Kent, Gabriella is 52nd in line to the throne.
On the other hand, Harry is sixth in line to the throne and the brother of the future King.
Nevertheless, there were plenty of famous faces in attendance, including Queen Elizabeth II herself and Prince Philip.
Prince Harry also attended the wedding sans Meghan, who was heavily pregnant at the time.
The bride's parents were obviously there, along with her brother Lord Frederick of Windsor.
Kate's sister Pippa Middleton, who is said to have once dated the groom, was also in attendance with her husband James Matthews.
Her parents Carole and Michael Middleton were also in attendance, and brother James Middleton with his girlfriend Alizee Thevenet.
The Queen's daughter Princess Anne and son Prince Edward also attended, as did Prince Andrew and Sarah Ferguson.

However, Andrew's daughter Princess Beatrice was there with her boyfriend, now fiance, Edoardo Mapelli Mozzi, who she was scheduled to marry on May 29 this year, but sadly the wedding was postponed due to the coronavirus pandemic.
Gabriella ‒ who now goes by the name Lady Gabriella Kingston ‒ is a freelance writer, who contributes to The London Magazine, among others.
She previously worked as a Senior Director at Branding Latin America, where she specialised in arts and travel.
Her husband Tom, a financier, proposed to her on the Isle of Sark, one of the Channel Islands, in August 2018.
On her wedding day, she wore a tiara worn by her mother Princess Michael of Kent, and her paternal grandmother, Princess Marina of Greece and Denmark.
Gabriella's mother Princess Michael is the former Baroness Marie Christine von Reibnitz, who took on the royal title of her husband in 1978.
Because she is a divorced Catholic, Prince Michael had to give up his right to succession to the throne in order to marry her, as per the Act of Settlement 1701.
However, this place was reinstated on March 26, 2015 with the coming into force of the Succession to the Crown Act 2013.
However, because Gabriella and her brother Frederick were brought up as members of the Church of England, they have been in the line of succession to the throne since birth.
Frederick married Sophie Winkleman in 2009 and they have two daughters together, Maud and Isabella.
