British musician Mark Ronson, the late Amy Winehouse’s legendary producer, married lingerie model Josephine de la Baume in a French ceremony during the first weekend in September. The couple began dating in 2009 and celebrated their union in Aix-en-Provence, France, at the Villa Gallici, near where de la Baume was born. Zac Posen designed the Agent Provocateur model’s low-cut, off-the-shoulder, pearl-embroidered gown for the big day. Earlier, de la Baume told ASOS magazine, “He's an amazing friend and I love his dresses. They're so well fitted.” Unfortunately, Posen couldn’t attend because he was putting the finishing touches on his 2012 collection, which he’ll unveil at New York Fashion Week. Designer Charlotte Ronson, the groom's sister, told E! News she had to finish her line early in order to make it to the weekend. Fellow new brides Kate Moss and Lily Allen were in attendance, as were Sean Lennon and Mark's other sister, D.J. Samantha Ronson.
