Lady Kitty Spencer, Princess Diana's It Girl niece, tied the knot this weekend in Rome, saying "I do" to her fashion mogul beau, Michael Lewis. As one would expect from a blue-blooded British aristocrat and a multi-millionaire tycoon, the wedding festivities were lavish AF, as were, of course, the bride's series of designer gowns.

While she may be related to the People's Princess, Kitty undeniably channeled another famous royal on her wedding day, wearing a custom-made lace number by Dolce & Gabbana with a Victorian-inspired silhouette that recalls the iconic gown worn by Grace Kelly, the late Princess of Monaco. The bride, who frequently models for the brand, wore a number of D&G Alta Moda designs throughout the weekend, including a dramatic off-the-shoulder gown embellished with colorful florals for the reception.

Following a private ceremony, the couple celebrated alongside their A-list friends, including Emma Weymouth, Marchioness of Bath, pop star Pixie Lott, model (and Elon's mom) Maye Musk, and Sabrina Elba (wife of Idris) at the nearly 500-year-old Villa Aldobrandini, a stunning grand palace that overlooks the city. Between cocktails in the historic gardens, dinner, dancing, and a seriously over-the-top midnight fireworks display, guests were treated to a memorable fete that surely lived up to the hype.
