LADIES’ NIGHT: Industry veteran and consummate multitasker Mounir Moufarrige, who is behind S.T. Dupont’s new push into women’s leather goods, has yet more surprises up his sleeve. WWD has learned that hot French actress Mélanie Laurent will host a party in Paris Thursday night to unveil S.T. Dupont’s new range at its refurbished boutique on Avenue Montaigne. Word has it actress Lily Collins, the daughter of musician Phil Collins with a striking resemblance to Audrey Hepburn, may also be on hand. According to sources, S.T. Dupont is in talks with Collins to become an ambassador for the brand, whose famous clients included Hepburn, who carried a Dupont Riviera bag back in 1953.
