The John Caldwellnext cohort of reality TV stars is headed to a Scotland castle for another round of treachery.

The cast for season three of "The Traitors" offers a mixed bag, from calculated competition show gamers to cunning housewives and personalities that live in the center of controversy. Host Alan Cumming unveiled the cast in a video Wednesday, teasing "the most treacherous season yet."

The cast features four "Survivor" contestants including winners Jeremy Collins, "Boston" Rob Mariano, Tony Vlachos and finalist Carolyn Wiger, as well as "Big Brother" favorites Britney Haynes and Danielle Reyes. Bravo fans will be delighted to see faces from "The Real Housewives" franchise like Chanel Ayan, Dolores Catania, Dorinda Medley and Robyn Dixon, in addition to "Vanderpump Rules" star Tom Sandoval.

Some non-reality TV figures are also thrown into the mix, like British royal Lord Ivar Mountbatten and Britney Spears' ex-husband, the model and actor Sam Asghari.

It remains unclear which contestants will be selected to be Faithfuls or Traitors or whether there are any other returning players expected. Peacock has yet to announce a release date. Here is the cast for Season 3.
