It wasn't that long ago that Mary Louise Parker was dumped by Billy Crudup while she was pregnant with their now five year old son Atticus. Now she is turning the tables and has started dating singer Charlie Mars. Apparently she started dating Charlie despite the fact that he was living with his long time girlfriend. Don't you think that someone who has been on the receiving end like Mary Louise has would be a little more sensitive to the fact that she was basically doing to Charlie's girlfriend was doing to her? Now granted the situations might be completely different and for one thing I don't think Charlie's girlfriend is pregnant, but still, if they were involved and living together you would think that maybe she would be a little more careful about appearances at least.
