Mary-Kate Olsen is engaged to her boyfriend Olivier Sarkozy! Though 17 years apart in age, Sarkozy and Olsen have a lot in common, like also-famous siblings and an almost unseemly passion for Knicks basketball. Olsen is not believed to have made Sarkozy 300 sandwiches in exchange for his commitment, but she did manage his calendar. “Mary-Kate has made him a better father," Us reports. "She remembers all the kids' special events." May she get that Neil Lane, platinum-setting, cushion-cut diamond she’d been scoping and may future sister-in-law Carla Bruni wear The Row to the wedding.
