‘True Blood’ co-star Jessica Tuck has been upped to full series regular on HBO’s hit series.  The Alan Ball produced series has also added three new female characters to their always growing cast.

New cast members include Alexandra Breckenridge (‘Dirt’, ‘Life Unexpected’) who will play Daisy, a member of a wiccan group; Vedette Lim (‘As the World Turns’) will play Naomi, a cage fighter who participates in underground matches for money; and Janina Gavankar (‘The Gates’, ‘The L Word’) will portray Luna, a super-sexy public school teacher and shapeshifter who is first seen attending an informal gathering with others like her.

The series is currently in production on Season 4 which will begin airing Summer 2011.
