Courtney Ford has landed yet another key recurring role.

The actress - who portrayed Trinity's daughter on Dexter and, most recently, a graduate student on The Vampire Diaries - will come on board season four of True Blood as Andy sister, Portia Bellefleur.

As first reported by Deadline Hollywood, look for this southern beauty to run her own law practice.

Earlier this week, the show also announced that Fiona Shaw will play a local psychic who gets possessed by a witch. The fourth season of this HBO smash doesn't return until the summer of 2011.
