After splitting with Nate Lowman in 2010, Olsen, 26, begins dating Olivier Sarkozy, 43, the half brother of former French president Nicolas Sarkozy. Taking the romance public, the pair is snapped spending time with his daughter and canoodling at New York Knicks games. "Everyone has an opinion," she tells the Wall Street Journal of their age difference. "I find it's better to focus on what's in front of you."
After quietly dating for two years, Olsen and Sarkozy get engaged, which the fashion mogul confirms when she steps out sporting a sizable engagement ring. "They were engaged for a bit before it came out," a source tells PEOPLE of the couple, who celebrated their upcoming nuptials with a February vacation in Jamaica.
