7. Charlie Sheen and Brooke Mueller
Some people probably just shouldn't be married. Ever. Like Charlie Sheen, who bid adieu to wife number three this year. Things didn't look good for this couple - who wed in May of 2008 - after a Christmas 2009 incident where Charlie allegedly threatened Brooke with a knife. Charlie was charged with domestic violence, second degree assault and felony menacing. In court, he agreed to a plea bargain on lesser charges and was able to avoid jail time - he was ordered to rehab, probation and anger management. In May of this year, the couple signed a 43-page property settlement document in May which laid out what belonged to who and set up custody arrangements for the couple's twin sons, Max and Bob. It appears that Charlie's booze-fueled freak-out at New York's Plaza Hotel was the final nail in the coffin. On November 1, citing the ever-popular "irreconcilable differences", the couple officially filed for divorce. In the divorce settlement, Brooke gets primary physical custody of the boys, $55,000 per month in child support and a $758,000 "parting gift" - which I think is less than what Charlie makes for three episodes of Two and a Half Men!
