François-Henri Pinault is doing what he can to help rebuild Notre Dame Cathedral after the beloved landmark went up in flames on Monday.

The 56-year-old French billionaire and his father, François Pinault, have pledged to donate more than $100 million for the repairs of the cathedral. Pinault's 82-year-old father is worth an estimated $37.3 billion, according to Bloomberg’s Billionaires Index.

"My father and myself have decided to release a sum of €100 million from our Artemis funds [the family holding company] to participate in the effort that will be necessary for the complete reconstruction of Notre-Dame," Pinault said in a statement to French newspaper Le Figaro.

Meanwhile, Pinault's wife, Salma Hayek, shared a photo on Instagram of the fire, and threw her support behind the city of Paris. 

"As many others I’m in deep shock and sadness to witness the beauty of Notre-Dame turn into smoke. I love you Paris," the 52-year-old actress captioned her post. 

Hayek and Pinault have a home in Paris and were married in the City of Light on Feb. 14, 2009, at the City Hall of the Sixth Arrondissement, which is less than a mile from the landmark.
