Roman Abramovich’s ex-wife Dasha Zhukova is pictured with son Philip Stavros Niarchos for first time

Roman Abramovich’s ex-wife Dasha Zhukova has been pictured with her newborn son for the first time as she celebrates her 40th birthday.

The Moscow-born art collector and her billionaire shipping heir husband Stavros Niarchos, 36, welcomed baby boy Philip Stavros Niarchos, in March, 14 months after tying the knot in a lavish St Moritz ceremony. 

Philip, the couple’s first child together, is named after Stavros’ father, who is worth £2billion. Dasha also shares a son, Aaron, and a daughter, Leah, with ex-husband Abramovich, from whom she split in 2017.

Radiant Dasha looks every inch the proud mother in the candid snap, which was shared on Instagram by close friend Derek Blasberg to mark the mother-of-three’s milestone birthday.   

The adorable photo shows Dasha smiling over her shoulder at the camera while baby Philip sleeps soundly in her arms. Derek wrote: ‘Wishing a happy (40th!?) birthday to this hot momma’.

Fashion insider Derek, who counts Kate Hudson, Victoria Beckham and Kendall Jenner among his inner circle, also shared a snap of Dasha with older children Aaron and Leah. His Instagram tribute also featured a new photo taken while Dasha was pregnant.

Dasha and Stavros kept the pregnancy private and did not officially announce their plans to start a family.

Philip’s birth – and his name – was inadvertently announced on Instagram by close friend Diane von Furstenberg who shared a post in mid-March declaring: ‘Welcome to the world Philip Stavros Niarchos’. 

Speaking to the Daily Mail’s Sebastian Shakespeare last week, a friend said: ‘They’re delighted. After what has been a very difficult year, being so isolated from loved ones, this is the perfect way for them to start a new chapter.’

It was the perfect early birthday present for Dasha, whose friends Sara Foster and jeweller to the stars Jennifer Meyer also shared their well-wishes on Instagram. 

Sara and Jennifer both shared sweet throwback photos of Dasha to celebrate the birthday girl’s big day.

Dasha and Stavros had been friends for more than a decade but became a couple after her nearly 10-year marriage to Abramovich came to an end.

Stavros previously dated socialite and hotel heiress Paris Hilton, from late 2005 until March 2007. 

The businessman, who is part of the Greek shipping Niarchos dynasty, was also in relationships with actresses Lindsay Lohan and Mary-Kate Olsen, and model Jessica Hart. 

Upon their split, Dasha and Roman said they were committed to jointly raising their children together and working together as co-founders of the Garage Museum of Contemporary Art and the New Holland Island cultural center in St Petersburg. 

Court documents filed in New York show Abrahmovich and Zhukova finalized their divorced in August last year.

The settlement included the transfer of over $92 million worth of property to Dasha – including a four-storey mansion in Manhattan.

Dasha and Stravo’s relationship was all but confirmed back in January 2019 when he spent New Year’s Eve with her friends in Peru. 

The shipping heir joined music magnate David Geffen, supermodel Karlie Kloss and her venture capitalist boyfriend Josh Kushner, jeweler Jennifer Meyer and her frequent companion Mikey Hess, and screenwriter Erin Foster on a journey through the Amazon. 

Sources then revealed in July of that year that the couple were engaged, with one telling Page Six that they were openly discussing their plans to marry with friends at her birthday party in New York City.  

Royalty, Hollywood and some of fashion’s most famous faces were present at the couple’s wedding in January 2020 when they married in a specially erected marquee close to the main ski jump Olympaschanze. 

Among those present was Princess Beatrice and Edo Mapelli Mozzi, actress Kate Hudson and fashion designer Stella McCartney.

Pictures of the nuptials were not released at the time but have since emerged, showing the glamorous bride wearing a stunning white gown with a chic embellished coat over the top. 

Her new husband meanwhile looked dapper in a navy suit, complete with a white rose pinned to his lapel.  

In one picture the couple are seen with the mayor of St Moritz, Christian Jott Jenny.

Stavros’s father Stavros Jr and uncle Spyros are the largest private landowners in St. Moritz. 

The £6 million Swiss leg of the marriage was held 24 hours before scheduled with guests keeping the timing a secret with the main celebration was at the Kulm Hotel.

The bride was given away by her father Alexander Zhukov, a Russian businessman who is a British citizen.
