Having a much younger or much older significant other has become somewhat of a Hollywood tradition. From older actors reliving their youth with much younger ladies to cougars on the prowl for a boytoy, it seems age really is just a number for many stars.
The latest May-December romance that caught many people by surprise is between Mary-Kate Olsen, 25, and Frenchman Olivier Sarkozy, 42, (brother to former French president Nicolas Sarkozy).
"MK is constantly complaining about boys not being mature enough for her," a source told Us Weekly, confirming rumors that the pair is dating. "She got the kids out of her system. Now being a businesswoman dominates her time, and she is rarely impressed with guys."
Though their 17-year age difference is, well, quite large, the Olsen and Sarkozy's romance isn't the most shocking. Hollywood legend Dick Van Dyke, 86, married a woman 46 years his junior in 2012, while Hugh Hefner's girlfriend (and former fiancee) Crystal Harris is 60 years younger than him.
