During a visit to troops in Yugoslavia in 2004, Prince Louis met his future wife Tessy Antony. She was a member of the Luxembourg Army, on a mission connected to the NATO force in Kosovo. The couple had a son, Gabriel, born in March 2006. They married later that year, on September 26, 2006, in Gilsdorf, a small village in northeast Luxembourg. At the time of the wedding, Prince Louis relinquished his rights of succession, as well as that of any descendants. He retained his royal style and title, but his wife simply took on the surname ‘de Nassau’. A second son Noah was born in September 2007. In 2009, Tessy was created HRH Princess Tessy of Luxembourg, and their sons were made HRH Prince Gabriel and HRH Prince Noah of Nassau.

The family lived in the United States for two years, before moving to London where Louis and Tessy studied at Richmond American University. They both received their Bachelor’s degrees in May 2014, Tessy in International Relations, and Louis in Communications. The Grand Ducal Court of Luxembourg announced on January 18, 2017, that Prince Louis and Princess Tessy of Luxembourg plan to divorce. Their divorce was granted on February 17, 2017, in London where they lived, and finalized on April 4, 2019. Tessy was then known as Tessy Antony de Nassau.
Prince Louis received a master’s degree in psychosocial studies at Birkbeck University in London. He then attended the Catholic University of Paris, studying to be a mediator, and received the international certificate issued by The Center for Effective Dispute Resolution. In 2020, Louis set up his own mediation company, SIBE Mediation, with three partners in Paris, France, merging the expertise of mediators with that of psychosocial and legal professionals.
On April 6, 2021, the Grand Ducal Court of Luxembourg announced the engagement of Prince Louis of Luxembourg and Scarlett-Lauren Sirgue. Scarlett-Lauren is the daughter of Pierre Sirgue, a French lawyer specializing in health law, and Scarlett Berrebi, a French lawyer specializing in family law. Scarlett-Lauren was a lawyer in her parents’ law firm, and Louis worked as a mediator in the same law firm. Less than a year later, on February 22, 2022, the couple announced that they were amicably ending their four-year relationship. Louis and Scarlett-Lauren issued an official statement that said: “We have decided not to pursue our romantic relationship while remaining deeply bound by friendship and tenderness. It is a decision we have made together upon serious reflection.”
