Lady Kitty Spencer has spoken out for the first time since her wedding which her father, Earl Spencer, was unable to attend.

Last Saturday, Princess Diana’s niece was escorted down the aisle by her two brothers when she married Michael Lewis in a lavish wedding in Italy.

In a magnificent ceremony in Rome, the 30-year-old married Mr Lewis, a rich father-of-three who is more than twice her age.

Kitty took to Instagram for the first time since the wedding to thank her half-brothers, Louis Spencer, Viscount Althorp, and Samuel Aitken, who walked her down the aisle since her father was unable to attend.

She wrote: “The proudest moment of my life, without a doubt, was having my brothers walk me down the aisle.

“Thank you to our family and friends for the most unforgettable weekend filled with more love and laughter and happiness than I have ever known.

“It still feels like a dream.”

There has been no official explanation for her father’s absence from her wedding, but a source close to the family has informed The Mail Online that the Earl’s absence might be owing to a shoulder ailment.

Hours before the wedding in Italy, he shared a photo shot in the grounds of his Althorp Estate,
captioned: “Now, that’s a moon.”

The source told the Mail Online: “Charles recently suffered an injury and perhaps that will be the reason for him not travelling, but it is just easier for everyone that he is not there.”

Diana’s brother addressed the injuries earlier this year in an interview with MSN, stating it as the reason he had to cancel a diving excursion related to his book The White Ship.

Meanwhile, the newlyweds kicked off their festivities on Friday night with a dinner party at Rome’s prestigious Galleria Del Cardinale restaurant, surrounded by their aristocratic guests, before a sunset wedding.

Throughout the festivities, Kitty donned a variety of dresses designed by Dolce & Gabbana.

Kitty and Michael’s wedding was attended by her sisters Eliza and Amelia, former Strictly Come Dancing star Viscountess Emma Weymouth, and famous friends like Pixie Lott, Idris Elba’s wife Sabrina, and Mark Vandelli from Made in Chelsea.
