Hereditary Grand Duke Guillaume married Countess Stéphanie de Lannoy on 19 and 20 October 2012 in Luxembourg City. Not only was it an important event in Luxembourg, but it also marked the last wedding of the current generation of heir apparents.
On 19 October 2012, the Prince and the Countess were married in a civil ceremony conducted by the mayor of Luxembourg City, Xavier Bettel.

While Prince Guillaume wore his Luxembourgish military uniform, Stéphanie wore a stunning Elie Saab gown that was made of lace and satin and was encrusted with pearls. The gown had a four metre train and took seamstresses nearly 4,000 hours to create.
The couple are marking their eleventh wedding anniversary this year, and have two children together- Prince Charles, born in May 2020, and Prince Francois, born in March 2023.
