NEW YORK - They play brother and sister on "Dexter." Now in real life, Michael C. Hall and Jennifer Carpenter are husband and wife.

Hall's spokesman, Craig Bankey, said on Friday that the couple eloped in California on New Year's Eve. They'll walk the red carpet together at the Golden Globe Awards on Sunday - the first time publicly acknowledging their relationship.

Hall, 37, and Carpenter, 29, just finished the third season of "Dexter," the Showtime series in which Hall plays the murderous title character. They've been quietly dating for about a year and a half.

At their wedding, Carpenter's grandfather's wedding band was attached to her bouquet of white roses.
