Kitty's mother, Victoria, wasn't initially seen in any of the photos that surfaced during the three-day nuptials, either, prompting many to believe that she had also missed her daughter's big day.
But those rumours were soon put to rest by Kitty's sister Eliza, who posted a few pictures of their mother on Monday morning.

The bride remained silent on social media until Monday morning, when she shared a stunning picture of herself in her gorgeous Dolce & Gabbana wedding dress.
"Thank you from the bottom of my heart Domenico & Stefano for creating a gown beyond my wildest dreams for the most important day of my life. There are no words that could ever express my gratitude @dolcegabbana. #AltaModa #DGFattoAMano," she captioned the stunning photo.
