Emma Thynn, the Marchioness of Bath, showed off her figure in a black bikini as she took a dip in the sea at Le Club 55 in St Tropez on Monday.
The 40-year-old emerged from the water with her hair slicked back and wore oversized sunglasses to complete her beach look. Her black two-piece was described as barely-there, showing off her sculpted frame.
She was spending time at Le Club 55, an iconic beach club and restaurant. It was founded in 1955 by Bernard and Genevieve de Colmont and initially served as a makeshift canteen for Brigitte Bardot and the crew of the film Et Dieu... crea la femme. It remains a hotspot for celebrities today.
Husband's High Court win over son's inheritance
The seaside trip comes after legal battles at home for the couple. Emma's husband, Ceawlin Thynn, the 8th Marquess of Bath and owner of the Longleat estate, recently won a High Court bid allowing their nine-year-old surrogate-born son, Henry, to inherit part of his £157million fortune.
Henry was born to a surrogate mother in America. Lord Bath and Lady Bath had their second son via a surrogate in 2016 after Emma suffered from a rare inflammatory condition during her first pregnancy.
Henry's eligibility to benefit from three family trusts had been in doubt because the trusts use a pre-1970 common law definition of "children" that predates modern fertility treatments. He is genetically the son of the 52-year-old Marquess and Lady Bath, but the historical wording raised questions over his status.
At the High Court, Lord Bath had asked for a "blessing" to allow Henry to potentially inherit a share of the fortune.
Judge's ruling
Mr Justice Matthews ruled that it would be "unfair on Lord Bath and on Henry" to treat the boy as though he were not his father's son.
"Henry is the son of Lord and Lady Bath. Not only is he treated by them and will be treated by the world in general as a child of Lord and Lady Bath's marriage but he is also their genetic child," the judge said.
Henry's older brother, John, 11, would still inherit before him under primogeniture, which provides for a firstborn legitimate child to inherit their parents' estate. But it was argued that Henry could still stand to benefit from the trusts.
