Divorce- Richards vs. Sheen

It's certainly one of the more volatile divorces in Hollywood. Some weeks, Richards and Sheen are at war; other times they're cordial. We're told they have just gone through a rough patch, but are now talking again. But it is an uneasy calm.

Richards filed for divorce in March 2005, citing irreconcilable differences. We're told that there was not one single problem leading to the split -- rather, it was cumulative. The couple has two children; Denise is asking for custody.

Richards and Sheen attempted a reconciliation last fall, but it failed.
