A former Miss UK has won Britain's biggest divorce settlement after splitting from her billionaire husband.
Kirsty Bertarelli, 50, secretly divorced Swiss tycoon Ernesto Bertarelli, 56, after being married for 21 years.
It is understood the couple, who have three children, separated this year and their divorce was agreed in summer.
A spokesman for the Bertarellis told the Daily Mail : "It is with sadness that Ernesto and Kirsty Bertarelli confirm that they have divorced.
"The decision was a shared one and the separation amicable."
Kirsty and Ernesto Bertarelli were listed in 14th place in this year's Sunday Times Rich List, with a fortune of £9.2billion, making her Britain's richest woman.
The former Miss UK agreed to accept a £350million settlement in the divorce, according to reports - although this detail was not confirmed by the couple.
The newspaper also reports that Mrs Bertarelli was given a house by Lake Geneva in Switzerland that the family bought this year for £52million.
It would make her the richest British-born divorcee in legal history.
By comparison, the Queen's worth is estimated to be about £365 million.
She also owns a chalet in the Swiss town of Gstaad, which is worth £8million and a mansion in Knightsbridge, Central London.
A friend told the Mail: "The settlement was more generous than it had to be. They didn't want a long, drawn-out court case in Switzerland and he wanted to recognise the length of their marriage."
In 2012, Mr Bertarelli commissioned the largest private motor yacht ever built in the UK for his wife, who then took charge of the £100million 314ft Vava II.
Mrs Bertarelli's family is one of the world's biggest manufacturers of ceramic products, Churchill China, in Stoke-on-Trent.
She was crowned Miss UK in 1988 and became a successful singer-songwriter after moving to London.
She met Mr Bertarelli at a dinner party in Sardinia in 1997 and the couple married in 2000.
The couple's spokesman said: "All issues arising from the divorce have been settled and they would respectfully ask for privacy for their whole family at this time.
"As this is a private matter, there will be no further comment."
