Good luck guessing what Natalie Portman is going to do next. The star isn't known for sharing much about her private life, but when she does she drops some doozies. In December 2010, the actress caught fans off guard with her out-of-the-blue engagement to French dancer Benjamin Millepied, which was announced at the same time as her first pregnancy. Portman keeps her personal life so hush-hush that onlookers thought she and Millepied had wed months before they actually tied the knot in August 2012.
