She did not reveal the child's gender or name.
Kitty is the daughter of Diana's younger brother Charles Spencer and model Victoria Aitken.
It means the baby is second cousins to Princes George, Louis, Archie and Princesses Charlotte and Lilibet.
She married her billionaire fiance Michael Lewis in a lavish Italian ceremony in July 2021.
The bride and the groom exchanged their vows in front of their high-society guests at the Villa Aldobrandini, which boasts stunning views of Rome.
Fashion tycoon Michael is the chairman of South African Foschini group and owns the high street shops Whistles and Phase Eight.
The couple's relationship was first made public in August 2018 and they are believed to have met through former Defence Secretary Liam Fox.
Kitty stunned onlookers at the Royal Wedding in 2018 with comparisons to her aunt, Princess Diana.
The model was accompanied by her sister Lady Eliza, brother Louis and mother Victoria at the wedding in Windsor.

She received rave reviews for her outfit. She teamed her Dolce & Gabbana dress with a burnt orange clutch bag and heels.
Princes Harry and William have remained close to their mum's family and were keen for them to be part of their big days.
Kitty first hit the headlines in 2016 when confessed she admires the homeless because they have a focus to their lives that she lacks.
Despite being part of the Spencer dynasty, worth £100million, the glamorous socialite says she struggles with having no purpose in life.
She told The Times: "The young people are so focused on one thing.
"They know exactly what they want to do and what their talents are. So for that, I envy them."
Kitty spent most of her childhood in South Africa as part of her father’s bid to keep her out of the spotlight following the death of her aunt in 1997.
She studied Art History in Italy before returning to London to pursue a career in modelling and made her debut in 2017 with Dolce & Gabbana.
