LOS ANGELES (AP) 鈥 鈥淭he Traitors,鈥 a reality/competition show hybrid, has announced a lineup of reality television all-stars, actors and even a British aristocrat for the cast of its upcoming season.

A slew of stars from the 鈥淩eal Housewives,鈥 鈥淪urvivor,鈥 the 鈥淏achelor鈥 franchises and more popular television shows will join host Alan Cummings for the upcoming third season of the Peacock hit.

The ensemble of television personalities and familiar faces will move to a castle in the Scottish Highlands to play a high-stakes murder mystery game and complete challenges to build up a grand prize pot of up to $250,000. While there are 21 contestants on the upcoming third season, some of them will be undercover 鈥渢raitors,鈥 trying to sabotage the group and keep their treacherous identity hidden so they can claim the prize for themselves.

Chrishell Stause, a real estate agent and actor known for her appearances on 鈥淪elling Sunset,鈥 leads the crew of newcomers from reality series. The casting of Tom Sandoval, on the 10th season of 鈥淰anderpump Rules,鈥 has also garnered attention given his antagonistic personality on the Bravo show.

Actor and model Sam Asghari, of Britney Spears, is also joining the cast. Asghari and Spears鈥 divorce was finalized in early May, nearly two years after they were married.

Four stars of the Bravo 鈥淩eal Housewives鈥 franchises will come together on the show, including Dorinda Medley (鈥淭he Real Housewives of New York City鈥), Chanel Ayan (鈥淭he Real Housewives of Dubai鈥), Dolores Catania (鈥淭he Real Housewives of New Jersey鈥) and Robyn Dixon (鈥淭he Real Housewives of Potomac鈥). Gabby Windey and Wells Adams are slated to join the crew from 鈥淭he Bachelor鈥 spinoffs.

The show's mix of mind games and missions could give an edge to the 鈥淏ig Brother鈥 and 鈥淪urvivor鈥 alums. Britney Haynes and Danielle Reyes are 鈥淏ig Brother鈥 fan favorites and Carolyn Wiger, Jeremy Collins, Rob Mariano and Tony Vlachos hail from 鈥淪urvivor.鈥

Other reality stars rounding out the cast include Bob The Drag Queen from 鈥淩uPaulsa国际传媒 Drag Race,鈥 Bob Harper from 鈥淭he Biggest Loser,鈥 Ciara Miller from 鈥淪ummer House鈥 and Nikki Garcia, a WWE star and professional wrestler. Dylan Efron, brother of and an actor and producer, is also set to join.

The final cast member joining the popular series is perhaps the one who will be most out of place: Lord Ivar Mountbatten, a member of the extended British royal family. He is also the first relative of the royal family to publicly come out as gay, according to .

The first two seasons of 鈥淭he Traitors鈥 were hugely successful for Peacock, with the first season taking home the Emmy Award for outstanding casting for a reality program.

Tapping into the respective, and at times, disparate, fanbases of each of the reality series the contestants are known for, 鈥淭he Traitors鈥 attracts a vast audience. The drama of 鈥淩eal Housewives鈥 combined with the betrayals of 鈥淏ig Brother,鈥 the tests of physical endurance a la 鈥淪urvivor鈥 and the motley crew of divergent personalities makes for good TV. Top that all off with Cummingsa国际传媒 dramatic flair and show-stopping fashion as the host, and the show has engaging elements for viewers with a variety of interests.

In addition to the popular U.S. version of the show, Peacock streams international versions including Australia and the U.K.

Peacock has not yet announced a release date for the third season.
