Dexter star Michael C. Hall has secretly married Jennifer Carpenter, the actress who plays his sister in the hit show.

The co-stars exchanged vows in Big Sur, California on New Year's Eve (31Dec08), after dating discreetly for a year and a half, Hall's representative has confirmed. The ceremony was so secret, even friends and family members weren't invited.

Hall's representative Craig Bankey tells AccessHollywood.com, "While not in attendance, family and loved ones shared in a celebratory toast to the couple."

Bankey confirmed Hall, 37, and Carpenter, 29, will step out for the first time as husband-and-wife at the Golden Globe Awards on Sunday (11Jan09). (IG/WNVACC/KL)
