On May 27, 1987, Prince Jean married Hélène Vestur at the Church of Saint-Philippe-du-Roule in Paris. Jean had given up his succession rights the previous year, just after the birth of the couple’s first child. So upon marriage, his wife and children simply took on the surname ‘de Nassau’ with no royal style or title. In 1995, they were raised to Count/Countess of Nassau, and in 2004, Grand Duke Henri elevated the children to Prince/Princess of Nassau, with the style of Royal Highness. However, they do not have any succession rights. Jean and Hélène divorced in 2004. The couple had four children:

  • Princess Marie-Gabrielle of Nassau (born 1986), married Antonius Willms, had two sons
  • Prince Constantin of Nassau (born 1988), married Kathryn Mechie, had one son
  • Prince Wenceslas (born 1990)
  • Prince Carl-Johan (born 1992)

In 2009, Prince Jean married Diane de Guerre at the City Hall in Roermond, the Netherlands. She holds the title of Countess de Nassau. They have no children.

Prince Jean does not undertake any official duties for the Grand Duchy of Luxembourg, however, he is often in attendance at private family functions. He works with the GDS-Suez Group and serves as Executive Vice President of the Suez Foundation, and a member of the board of Degrémont, a company that specializes in the production of clean and healthy drinking water. Degrémont is a subsidiary of Suez Environnement, SA. Continuing with his work in the area of water sanitation, Prince Jean purchased a subsidiary of Suez Environnement in 2006, and created Mea Aqua. This organization is focused on developing water and energy solutions in the Middle East and Asia.
