The glamorous two-day ceremony in the small French town of Aix-en-Provence was attended by celebrities such as model Kate Moss and singer Lily Allen.
Ronson wore a pink candy-striped suit complete with Ray-Ban sunglasses at the nuptials, while de la Baume wore a low-cut gown by American designer Zac Posen, creator of the wedding dress featured in the upcoming film, Breaking Dawn.
In an interview with ASOS Magazine, she commented on Zac Posen and the gown he designed for her: “He’s an amazing friend and I love his dresses, they’re so well fitted. I’m really excited and he’s so excited about it.”
The fashionable couple first met in 2009. Ronson popped the question to his girlfriend in New York earlier this year. The newlyweds now plan to split their time between Paris and New York, with trips to London.
Josephine de la Baume first became known through the modelling she did for London-based lingerie company Agent Provocateur.
