One of Hollywood's most enduring urban legends is the 'Oscar Love Curse.' It suggests that women who win the Best Actress Oscar are destined to see their marriages or relationships collapse shortly after. While it sounds like supermarket tabloid fodder, researchers at the University of Toronto and Carnegie Mellon actually studied the phenomenon in 2011. They found that Best Actress winners are indeed at a 63% higher risk of divorce than those who are only nominated. Famous examples cited include Reese Witherspoon, Halle Berry, Sandra Bullock, and Kate Winslet, all of whom split from their partners within a year of winning. The study suggested that the sudden 'status shift' and professional success can sometimes create strain in traditional relationship dynamics.
