A pair of soap opera stars are heading to primetime.
Michael Graziadei (pictured, Daniel, The Young and the Restless) and Finola Hughes (Anna, General Hospital) will both guest star on the February 3 episode of the CBS drama.
During the hour, a young woman's body is found, drained of blood. This brings the investigation into the dark and mysterious subculture of vampirism, as Graziadei appears as Keith, the grieving boyfriend; and Hughes portrays the victim's mother.
Last month, Vanessa Minnillo and Kim Kardashian guest-starred on an episode of the series.
