Mark Ronson married Josephine de la Baume Saturday in Aix-en-Provence, France. He was decked out in a red and white seersucker suit for the ceremony while Josephine's dress was made by pal Zac Posen. Many of Mark's famous relatives came out, including his sisters Samantha, Charlotte, and Annabelle. There were other well-known guests at the event like models Irina Lazareanu, Charlotte Kemp Muhl, and her boyfriend, Sean Lennon. Kate Moss and Lily Allen apparently turned out, too. Mark and Josephine have been engaged since February — congrats to the happy couple!
