Francois-Henri Pinault, Salma Hayek's multi-billionaire husband fathered supermodel Linda Evangelista's 4-year-old son.

Evangelista was tightlipped about Pinault's paternity back in 2007.

According to reports, Hayek and Pinault met in May 2006, announced their engagement and her pregnancy in 2007, broke up in 2008, reconciled and were married on Valentine's Day 2009.

Evangelista's son was born in October 2006, which means that her baby was conceived before Hayek and Pinault had even met. Pinault, who is the CEO of a company that owns Gucci and Yves Saint Laurent, in addition to his daughter with Hayek, also has two children from a previous marriage. He is yet to publicly acknowledge Evangelista's son as his.

Both the tycoon and his actress wife has previously insisted in interviews that Pinault has only three children - Valentina and two from his previous marriage to his first wife - and the father of her son was 'a New York architect', an ANI report said.
