WASHINGTON — The hit Peacock series “Traitors” returns with an all new group of contestants in the Scottish Highlands.

Olympians, Housewives, reality show winners and a football mom are all heading to the castle for Season 4 of the Emmy-winning show.

Alan Cumming reprises his role as host, introducing 23 fresh contestants to a new season of intrigue and deception. This year’s lineup features Olympic figure skaters Tara Lipinski and Johnny Weir, alongside Real Housewives celebrities like Lisa Rinna, Porsha Williams, and Dorinda Medley. Additionally, Big Brother winners Tiffany Mitchell and Ian Terry join the fray.

Donna Kelce, the mother of NFL icons Travis and Jason Kelce, is also making an appearance. Other participants include K-pop star Eric Nam, comedian Ron Funches, and actor Michael Rapaport.

The series will adhere to its established format. Contestants are split into the roles of Faithful and Traitors. Each night, the Traitors covertly “murder” contestants, while the Faithful collaborate to identify and eliminate them. If all Traitors are discovered, the Faithful claim the $250,000 prize. However, if even one Traitor remains undiscovered by the end, they capture the entire prize fund.
