It's taken billionaire Francois-Henri Pinault "over a year to get Salma to agree to marry him, and he doesn't want to spare any expense. Francois basically gave her the key to the vault and said, 'Go wild.'"

The pair are planning a 5 day wedding ceremony in St. Tropez, France.

The National Enquirer claims the pair will fly their friends in on private jets; put them up in luxury resorts; spend $500,000 on a wedding dress and almost $1 million on flowers.  That's a lot of daisies, darlin'.
