Oscar love curse

The Oscar love curse or Oscar curse is a superstition that the woman who wins the Academy Award for Best Actress will have her boyfriend, fiancé, or husband cheat on her or divorce her soon after. It has also been applied to the Best Supporting Actress.
In their paper published in "Organization Science", Michael Jensen and Heeyon Kim use the "Oscar Curse" to examine the negative consequences of upward mobility following a sudden positive status shift. With an empirical study, the authors find "Oscar nominations/wins have positive professional consequences for male and female actors but more enduring negative personal consequences for male actors, thus emphasizing an important conundrum for male actors: Oscar nominations/wins can help a career but can also ruin a marriage."
Exceptions.
Some actresses have managed to "break" the curse. On even rarer occasions, actresses (e.g., Maggie Smith) both experience and break the curse.
