Mary-Kate Olsen has married her long-time boyfriend, Olivier Sarkozy, in a ceremony. Mary-Kate, who became a popular child actress with her twin sister, Ashley, on the TV series "Full House," before moving on to become a designer, has been dating French banker Sarkozy since 2012. As his last name suggests, he is the half-brother of former French President Nicolas Sarkozy, 46. Despite a 17-year age difference between him and Mary-Kate, 29, the couple live together in New York and announced their engagement in March of last year. The ceremony took place on the 25th (local time) at a mansion in Midtown Manhattan with around 50 guests. Guests were asked to leave their cell phones and electronic devices behind, and enjoyed cocktails in the mansion's garden before settling down for dinner. Due to the couple's desire to value privacy, details about the guests and Mary-Kate's wedding dress are still scarce, but we wish the couple, who have been together for three years, every happiness in the future.
