GARCELLE & MICHAEL

Don't cross a woman scorned, not when her name is Garcelle Beauvais. The actress sent an angry e-mail titled "Tiger Woods/Jesse James/Mike Nilon" to her husband's Creative Artists Agency colleagues in May, exposing his alleged infidelity. Beauvais wrote, "What do they have in common ... I found out today that MY husband of almost 9 yrs has been having an affair for 5 yrs with some slut in Chicago. I am devastated!!!!" A month after her public accusation, Beauvais officially filed for divorce from Nilon, seeking joint custody of their twin boys.
