Wildenstein was born as Jocelyne Alice Périsset in
Lausanne, Switzerland. Her father, Armand Périsset, worked in a sporting goods store and her mother Liliane Périsset was a housewife. She began dating Swiss Cyril Piguet, producer of the 1964 film
Un commerce tranquille, at the age of 17. She later lived in Paris with Italian French filmmaker
Sergio Gobbi. While there, she became a skilled hunter and pilot. Périsset was introduced to
Alec N. Wildenstein, of the family of wealthy art dealers, by Saudi arms dealer
Adnan Khashoggi at a shooting weekend at the Wildenstein ranch "Ol Jogi" in Kenya in 1977. The Wildensteins' divorce in 1999 was not amicable. Jocelyn walked in on her husband and a 21-year-old Russian model in her bedroom at the couple's
New York City home, and he threatened Jocelyn with a gun. This resulted in a night in jail for Alec Wildenstein. The presiding judge, Marilyn Diamond, received death threats in the mail during the proceedings. During her divorce, the judge stipulated that she could not use any
alimony payments for further cosmetic surgery. Jocelyn enlisted the services of
Ed Rollins for public-relations assistance and at various times both Bernard Clair and Kenneth Godt for legal counsel. Wildenstein began dating fashion designer
Lloyd Klein in 2003. == Cosmetic surgery ==
