6. Arnold Schwarzenegger & Maria Shriver. Who would have thought that after 25-years of marriage Arnold Schwarzenegger and Maria Shriver would get a divorce? Well, probably Arnold's housekeeper, mistress and baby mama. But come on, that's like 1 in a few million. When news broke that Arnie and Maria had separated in May, we needed to know why. Turns out Arnold had himself some fun on the side with their housekeeper, which included a son he kept hidden for 10-years. Maria officially filed for divorce in July and hasn't looked back since. At least we assume she hasn't. Sadly I don't have Maria on my speed dial to ask her.
