Newlywed Kitty Spencer has told how being walked down the aisle by her brothers was the ‘proudest moment of her life’ - but made no mention of her absent dad, Charles Spencer. Princess Diana's niece, 30, who tied the knot to retail millionaire Michael Lewis, 62, at a 17th century Italian castle last Saturday, took to Instagram to write: '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.'
