SORRY, CHARLIE

Here's one reunion that wasn't canceled by Fox: Charlie Sheen and Denise Richards, who reportedly were on their way toward a reconciliation after first filing for divorce last March, aren't, it turns out. According to TMZ.com, lawyers for both sides filed divorce papers on Wednesday, asking that the case be handled in private arbitration. The buzz is that the couple once again hit the skids, seemingly for good, over the holidays. Chuck, I warned you: A blender is not a romantic Christmas gift.
