Jennifer Carpenter and Michael C. Hall, who play brother and sister on the Showtime series Dexter, are ending their two-year marriage.

"Having been separated for some time, Jennifer Carpenter and Michael C. Hall have filed for divorce," their reps said in a joint statement.

The announcement comes just one day after Carpenter attended the Dexter season finale party without Hall, Access Hollywood reports.

Jennifer Carpenter and Michael C. Hall are over.

Carpenter famously stood by Hall's side during his battle with Hodgkin's lymphoma, and they couple married on New Years Eve 2009.

She gushed that he's "the sexiest man alive, one of the best we've got. He's incredible and if anyone deserves accolades, it's him."

Here's wishing the couple the best in this tough time.
