The eldest daughter of Earl Spencer, 33, announced she had secretly given birth to her first child with husband Michael Lewis, 65, in March.

Although Kitty didn't confirm her baby's gender in her Mother's Day post, her younger sister Lady Eliza gushed about her 'perfect little niece' in the comments.

Lady Kitty captioned the image: 'Athena watching the world go by.' The post has amassed over 32,000 'likes' in the past 24 hours - and fans gushed over the 'beautiful' moniker.

One wrote: 'Oooh darling... Athena is so gorgeous!! Like her mama.' 'Congratulations,' another added. 'She is so precious. I love her name.' 

'What a fantastic Greek name,' a third said. Kitty's sister Lady Amelia added: 'Perfect angel.'  Meanwhile, Lady Eliza wrote: 'Puppy!'

Lady Kitty, then 30, wed the multi-millionaire Michael Lewis at the Villa Aldobrandini in Frascati, a stunning country mansion with views out towards Rome, on July 24, 2021.

Having delayed their wedding for two years due to the pandemic, the celebrations stretched across three days and were attended by close friends including the pop star Pixie Lott and the Marchioness of Bath.

The bride, a Global Brand Ambassador for Dolce & Gabbana, wore five gowns by the designer over the weekend.

For her main wedding dress, Kitty opted for a high-neck, Victorian-inspired white lace gown featuring feminine puff sleeves and a cinched waist. The design drew inspiration from her mother Victoria Lockwood's own wedding dress with its button-down front.

Designer and co-founder of the fashion house, Domenico Dolce later said of Kitty's wedding wardrobe: 'She told us she had thought of us immediately, and we were very happy with that!'

'They've been beautiful and emotional moments,' said Dolce. 'One of the inspirations is definitely her love for Italy. Kitty is in love with our beautiful country and its rich history, art and culture.'

Stefano Gabbana said: 'But she is also a girl who is very attached to her origins, to England; to her heritage of the great Victorian era. And like all the English people, she has a great passion for all kinds of flowers.'

The famous Spencer Tiara worn by Princess Diana was missing from the ceremony. Instead, Kitty opted for an elegant veil, intricate headpieces and flower crowns that each complemented the respective gowns.

The couple exchanged vows in between floral arches. Music was provided by a pianist and a singer positioned to the right of the couple.

Mr Lewis wore a kippah, and it is thought Lady Kitty received instruction in the Jewish faith ahead of the ceremony.

The smiling newlyweds walked back down the aisle hand-in-hand as guests tossed pastel-coloured confetti in the air.

The celebrations continued into the evening with dancing and a live band and the night ended with a spectacular fireworks display.
