TV Guide is reporting that Dexter stars Michael C Hall and Jennifer Carpenter are filing for divorce. They were married New Year’s Eve in 2008 (so that didn’t even last 2 years.) It doesn’t seem like there is any other information at this time but check out the link below for more details.
I wonder how something like that affects them on set? I would say not much because they are professionals and if they have been separated for some time, you would have noticed it this season, if it would have effected them.
