Eleonore von Habsburg has announced the birth of her third child with her former Formula One racing driver husband Jérôme d’Ambrosio.

The daughter of Karl von Habsburg, head of the House of Habsburg-Lorraine, took to Instagram to share the joyous news by posting a series of pictures captioned with a Roman numerals date.

Featuring a sweet photograph of her newborn daughter's fingers, Eleonore, 32, whose full title is the Archduchess of Austria, revealed that the couple's child is called Cosima, born on July 4.

Baby Cosima is Eleonore and Jerome's third child following the birth of their son Otto in October 2021, followed by their first daughter Zita in 2024.

Otto is named after the Archduchess' paternal grandfather, Otto, Crown Prince of Austria, and her paternal great-grandmother, Zita of Bourbon-Parma.

Eleonore, who is the great-granddaughter of the last Emperor of Austria, wed Jerome in 2020 at a registry office in Monaco, presided over by the Principality's Mayor, Georges Marsan.

Jerome, 40, has served as deputy team principal of Ferrari in Formula One and Head of the Ferrari Driver Academy since 2024, having retired from racing in October 2020.

The couple announced their engagement in March 2019 after two years of dating, and frequently take to social media to share snapshots into their luxury travel destinations across the globe.

Born in Salzburg, the glamorous model and socialite is the daughter of Archduke Karl von Habsburg - head of the House of Habsburg-Lorraine and a leading politician - and his estranged wife, Baroness Francesca von Habsburg.

This makes Eleonore the great-granddaughter of the last Emperor of Austria, Charles I of Austria, who reigned for two years until the monarchy was abolished at the end of the First World War.

At its height of power, the House of Habsburg was one of the leading and most influential rulers in Europe.

The couple had planned a large church wedding but due to coronavirus restrictions, they opted for a smaller civil ceremony at a registry office.

Despite Eleonore's royal connections, she previously told Madonna24 how her parents have always insisted that she and her siblings stay 'grounded' and she loves shopping in high street stalwarts such as Mango, Zara and H&M.

'I am incredibly grateful to my parents for not raising us in the belief that it is normal to go to Swiss boarding school and to live in London in a chic apartment,' she told the site.

Eleonore has been with d’Ambrosio, since early 2017 and has close links to the racing world with her brother, Ferdinand Habsburg, an acclaimed endurance racer who recently reclaimed victory at Le Mans.

The eldest of three children, she attended boarding school in Gstaad, Switzerland before studying law at London's European Business School.

The brainy aristo beauty speaks fluent German and English, and is reportedly proficient in French and Spanish too.

And it seems fashion runs in the family as her mother, who descends from Swiss nobility, also enjoyed a brief spell as a model before pursuing a career as an art collector.

It is not known whether she has pursued a career in law, however she has risen to prominence in the fashion world with high-profile campaigns for the likes of Dolce & Gabbana under her belt.

She was hand-picked to star in the Italian luxury label's SS18 runway show in Milan alongside other society beauties including Lady Kitty Spencer, Lady Amelia Windsor and Maria-Olympia of Greece and Denmark.

But she insists she does not have her sights set on modelling, telling Madonna24: 'It was a great experience - but the model business is definitely not my main career path.'
