Spending a year married to Gregory House can turn a woman into a real bloodsucker.

Case in point: Karolina Wydra — who played Dominika, the convenient bride of Hugh Laurie’s titular doc on Fox’s House — is joining True Blood‘s sixth season as a badass vampire, TVLine has learned exclusively.

Wydra’s recurring character, Violet, is described as a strong, sexy, possibly dangerous vamp on par with the Eric Northmans and Bill Comptons of the world.

Also joining the HBO smash in Season 6 is acting vet Rutger Hauer (as a mysterious figure with deep ties to Sookie and Jason), Rubicon’s Arliss Howard (as Louisiana Governor Truman Burrell), Friday Night Lights grad Jurnee Smollett-Bell (as do-gooder Nicole) and 90210‘s Amelia Rose Blaire (as Howard’s onscreen daughter).

Wydra will next be seen in the sci-fi thriller Europa Report, to be released later this year.

True Blood‘s sixth season is slated to premiere in June.
