Very surprising news today from one of television's most anticipated new shows:

True Blood alum Lucy Griffiths has been let go from Constantine, the upcoming NBC series based on a comic book character who fights supernatural crime, after producers decided her role of Liv simply didn’t fit with the show.

Griffiths is introduced as a key cast members of the pilot, with Liv a daughter of one of John Constantine’s dead friends.

In place of Liv, the drama will add Zed, a psychic who teams up with Constantine to battle various evil forces. No word yet on who will take on this new role.

UPDATE: Telemundo star Angelica Celaya has been cast in the new role of Zed.

Constantine will air on Friday nights and to premiere on October 24 at 9/8c on NBC.
