DailyMail.com exclusively reported that Dasha, 38, and Stavros, 34, said ‘I do’ in a specially erected marquee close to St. Moritz’s main ski jump Olympaschanze.
Stavros’s father Stavros Jr and uncle Spyros are the largest private landowners in St. Moritz, with a source telling MailOnline: ‘The Niarchos family are hugely respected and valued in St. Moritz.
‘They could have held the wedding at any fabulous location in the world but have chosen St. Moritz because it is of great importance to them to support the town and the groom’s father is an honorary citizen.

Stavros, who is part of the Greek shipping Niarchos dynasty, has dated a list of celebrities in the past including Paris Hilton, Lindsay Lohan, Mary-Kate Olsen and had a seven-year relationship with Jessica Hart.
Dasha, 38, a successful Moscow-born businesswoman and art gallery owner and Stavros, 34, who was born in New York, had been friends for more than a decade but became a couple after her split in 2017 with Abramovich, with whom she had two children.
The source added: ‘St. Moritz affords the celebrities and guests security and privacy. What happens in St. Moritz stays in St. Moritz.

‘Locals do not generally bother the celebrity visitors. It is only a small town so it is virtually impossible to avoid bumping into them.
‘I expect locals will share a table with a few in the popular Salsastrains restaurants and not notice them openly. It is almost an unspoken code and one of the reasons the fabulously wealthy choose here for such celebrations.
‘St. Moritz itself is the most Swiss of all the Swiss ski resorts. It caters to an old money crowd including generations of Niarchos, Guccis and royalty from all over Europe and the Middle East as well as well as the horsey set.
‘It will be a fabulous party weekend and the folk who live here wish the happy couple all the very best and welcome them.’
