Dexter star, Michael C. Hall is reportedly dating his on screen sister Jennifer Carpenter.

The National Enquirer has reported that the recently divorced Hall has taken up with Carpenter, despite disapproval from the show bosses.

The paper also claimed that the two have been dating for almost a year, and even moved in together after Hall separated from his wife Amy Spangler.

A source says, “For months they tried to keep the romance a secret by going to out-of-the-way places and avoiding each other on the set. They still refuse to acknowledge they’re in a relationship, but everyone on the set knows they’re together.”

This is kind of like Doctor Who dating his daughter. It all feels a little bit wrong to me!!!
