Dexter and his sister on the show are now officially Arkansas brother and sister ;-) (I mean that in the most endearing way Arkansas readers). Michael C. Hall and Jennifer Carpenter, Dexter co-stars and on-set siblings, are officially dating.

The couple's friend said, "I don't see what the big deal is...They play brother and sister on the show, but they are actors, after all." Um, yeah, we get it.

In the words of some random guy that made it up, "Incest is best"...when you're actors that is.
