20. Andre Agassi and Brooke Shields
According to court documents, Andre Agassi and Brooke Shields' two-year marriage dissolved as a result of being "incompatible in their tastes, natures, views and dislikes..." Huh? Being polar opposites sounds like a good reason to get divorced, but an even better reason not to get married. Shields would later admit to legendary gossip columnist Liz Smith that, over the course of a year, the couple spent "three weeks, tops" together. Sounds like a recipe for eternal love, actually.
