Lady Kitty Spencer and billionaire Michael Lewis are tying the knot in Rome this weekend.

The daughter of Earl Charles Spencer (brother of the late Princess Diana) and Victoria Aitken first got engaged to Lewis in 2019.

While Kitty hasn’t mentioned the wedding on social media apart from posting adventures in Rome with her close friends, those same friends have been teasing the big day on Instagram.

Most of the guests are being outfitted by Dolce & Gabbana, while the bride took to Instagram to share a photo of herself in D&G gown (she is a model for the fashion label, and close friends with founders Domenico Dolce and Stefano Gabbana).

Villa Aldobrandini in Frascati just outside Rome even featured its own balcony with flowers for the newlyweds to have a royal inspired kiss.

It is unclear if any members of the Royal Family will attend the nuptials. Of course, Prince Harry and Meghan Markle are in California and while Italian reports claimed Prince William and Kate Middleton could make the trip for his cousin’s wedding, it appears they didn’t.
