Cape Town - Lady Gabriella Windsor married Thomas Kingston in a fairy tale ceremony – and the British royal family was there it witness it.

Just one day before the Duke and Duchess of Sussex celebrate their first wedding anniversary, British royals and family guests arrived at St George's Chapel in Windsor Castle to celebrate Lady Gabriella, affectionately known as Ella, and Thomas – including Queen Elizabeth and Prince Harry.

The 38-year-old British Royal – who is the daughter of Queen Elizabeth II's cousin, Prince Michael of Kent – stunned in a white Luisa Beccaria and a Russian Fringe-style tiara, a family heirloom, as she arrived for her wedding on Saturday, British Vogue reports.

According to E! News, Anne, Princess Royal and Andrew, the Duke of York were also in attendance, alongside Sarah Ferguson as well as Princess Beatrice and her boyfriend Edoardo Mapelli Mozzi.
