So how much is the bride-to-be worth?
What is Lady Gabriella Windsor’s job?
The professional has worked as a journalist, after getting a degree in Comparative Literature from Brown University in the USA.

As she is a privately employed individual is difficult to asses just how much Lady Gabriella is worth.
What is clear, however, is that as a British royal she lives a life of wealth and privilege.
She attended private schools and grew up living in Kensington Palace.
Her father, Prince Michael of Kent, is the first cousin of Queen Elizabeth II.
He is said to be worth around $40 million or £31m.
Lady Gabriella Windsor won’t have a reception held by the Queen after her ceremony, unlike Meghan and Princess Eugenie.
Instead of the interim reception at Windsor Castle, Gabriella will have a reception at Frogmore House after.
Gabriella could wear the Kent City of London Fringe.
Given as a gift to her grandmother Princess Marina of Greece and Denmark, the gift would not be allowed today due to rules surrounding royal gifts.
However, it has also been suggested that she might wear the Kent Pearl Festoon Tiara, which her mother wore in the past.
