Michael C. Hall and Jennifer Carpenter play brother and sister on the hit series Dexter, but now will play ex-husband and wife in real life. The couple has filed for divorce after two short but eventful years of marriage that saw Hall battle Hodgkin's lymphoma and their critically-acclaimed show blow up.
"Having been separated for some time, Jennifer Carpenter and Michael C. Hall have filed for divorce," reps for the couple said in a joint statement.

Access Hollywood says the couple has been bickering on set for months and the rest of the cast and crew knew it was only a matter of time before a separation was announced.

Now producers are trying to figure out how the actors will be able to work as closely together as their characters require. Maybe Dexter will make Deborah his next victim?

Hall and Carpenter wed on December 31, 2009 in a New Year's Eve ceremony. They have no children. Hall was previously married to Broadway actress Amy Spangler.
