LOS ANGELES: Salma Hayek is set to marry her billionaire fiancé Francois Henri Pinault in a spectacular $3.5 million celebration next spring. The couple announced their engagement and Hayek’s pregnancy last year, which was followed by the birth of daughter Valentina in September.

Hayek and Pinault have enjoyed a low-key relationship, but sources tell the National Enquirer that the 46-year-old French boss of fashion houses Gucci, Yves St Laurent and Balenciaga will dig deep for a five-day-long wedding ceremony in St Tropez, France.

An insider reveals, “It took Francois 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 tabloid 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.
