She added, “Over the years, we shared so many special moments, and I will always be grateful for the care, love, and support you showed me along the way. I will always treasure the birthdays we celebrated, the time our families spent together, and all the precious memories we shared there.”

Jisoo concluded her message by writing, “Rest in peace, Mathilde. You will never be forgotten.”

According to the prosecutors’ office of Niort, Favier and Altmayer died on Monday near Niort after their car collided with an oncoming truck while they were overtaking another vehicle, Agence France-Presse reported.

Altmayer was known for producing films including The Conquest (2011), about former French President Nicolas Sarkozy’s rise to power.

France’s Culture Minister Catherine Pégard described him as a “producer with a keen eye” and praised Favier’s contribution to fashion and luxury.
