Lady Kitty Spencer’s wedding dress has been revealed after she got married to billionaire fashion businessman Michael Lewis.

The model, who is the daughter of Diana, Princess of Wales’s brother Earl Spencer, tied the knot with the tycoon wearing a decadent Victorian-inspired Dolce and Gabbana gown in Italy.

Dolce and Gabbana said the lace bridal gown was created exclusively for Lady Kitty, 30, “on the most important day of her life”.

It featured white lace, puff shoulders with a full skirt and floor-length veil, and she wore her hair slicked back.

The cousin of the Duke of Sussex and the Duke of Cambridge was appointed Dolce and Gabbana’s global ambassador earlier this year, and has been in a relationship with Mr Lewis, 62, for two years.

Lady Kitty, who reportedly walked down the aisle with her brothers Louis Spencer, Viscount Althorp, and Samuel Aitken, shared photographs of what appeared to be her hen do in Florence on Friday.

One photograph showed six women wearing brightly coloured wigs with their backs to the camera as they walked down a boulevard.

Celebrities including Pixie Lott, Idris Elba, Viscountess Emma Weymouth and Made In Chelsea’s Mark Francis Vandelli reportedly attended the star-studded wedding.

Mr Vandelli showed off the silver suit and white bow-tie he wore for the wedding on Instagram, with the caption “I’m coming for you Kitty Spencer” and heart emojis in the colours of the Italian flag.

Lady Kitty was born in England and raised in South Africa but spent much of her childhood at Althorp, where Diana also grew up, and which will be inherited by her younger brother Louis.
