Sofia Coppola was out with her fiancé, Thomas Mars, last night before hanging out with her youngest daughter, Cosima, today in Bernalda, Italy. Sofia, Thomas, Cosima, and Cosima's big sister, Romy, are in the small Italian town for Sofia and Thomas's Saturday wedding. The place holds special significance for the Coppolas — Sofia's great-grandparents used to live there. The Coppola-Mars family headed to Italy late last week, where they've been enjoying dinners out and some rest and relaxation as they prep for this weekend's nuptials. Sofia donned a strapless swimsuit as she spent time with Cosima and Romy at the beach, and her father, director Francis Ford Coppola, has been spotted in Bernalda, along with Sofia's brother Roman Coppola. Sofia is reported to be wearing Azzedine Alaïa for the big moment, which will take place in the gardens of Palazzo Margherita.
