It's been billed the society wedding of the year, and Lady Kitty Spencer's glittering guest list certainly justifies such a claim.
Princess Diana's niece, 30, married retail millionaire Michael Lewis, 62, at a 17th century Italian castle on Saturday, in a stunning lace gown by Dolce & Gabbana, for whom she is a brand ambassador.
Lady Kitty, daughter of Earl Spencer and his first wife Victoria Lockwood, dazzled in a series of gowns all made for her by fashion house, while the Italian duo also dressed many of her glamorous attendees.
Kitty was escorted at the ceremony, held in the gardens of the Villa Aldobrandini – a stunning mansion in Frascati, near Rome – by her brother Louis Spencer, Viscount Althorp, and half brother Samuel Aitken, whose father is businessman Jonathan Aitken. However there was also no sign at the festivities, which spanned several days, of her father, nor Kitty's cousins Princes William or Harry, whose weddings in 2011 and 2018 she attended.
Also understood to have been present were the groom's three grown-up children from his marriage to ex-wife Leola.
After the ceremony, the couple treated guests to a sumptuous dinner and dancing, before they took to the balcony to watch an incredible fireworks display. Here FEMAIL reveals the lucky list of attendees - from members of the British aristocracy to DJs, reality stars and catwalk royalty.
With a trousseau of five ever-more breathtaking dresses featuring yards of lace, silk and tulle, it was a wedding fit for a princess – the stuff of which fairytales are made

Eliza and Amelia Spencer - the bride's sisters
Twins Lady Eliza and Lady Amelia Spencer were there to watch their big sister down the aisle, accompanied by their partners.
Eliza recently marked her four-year anniversary with boyfriend Channing Millerd, with whom she often shares romantic selfies from exotic holidays.
Amelia got engaged to long-term love Greg Mallett last year, with Greg asking for their father Earl Spencer's blessing before proposing in South Africa.
Neither twin has shared any photos from the wedding as yet on their Instagram accounts, but they were spotted on the balcony with the bride and groom, and tagged in shots exploring Rome by half-brother Samuel Aitken.

Samuel shared a series of snaps from the family's time together in Rome ahead of the nuptials - though Louis appears to prefer to keep his private life (and Instagram account) private.
