Joanne McNally has joined the latest line-up for The Celebrity Traitors on BBC One, as the hit reality series prepares for its second season in the Scottish Highlands. The new series brings together 21 well-known figures who will compete in a psychological game of trust and deception.
The show returns under the guidance of presenter Claudia Winkleman. Once again, contestants will gather in an isolated castle where they must identify hidden Traitors within the group. At the same time, the Traitors attempt to secretly eliminate their fellow players during the night. Joanne McNally joins a diverse cast that includes actors, musicians, comedians and broadcasters. In addition, the line-up features Michael Sheen, Bella Ramsey, Ross Kemp and Myha’la, all of whom bring strong television experience to the competition.
The BBC also confirmed participation from Richard E Grant, Miranda Hart and Maya Jama. Furthermore, comedians James Acaster, Joe Lycett, Romesh Ranganathan and Rob Beckett add a strong comedy presence to the series. Meanwhile, the cast also includes James Blunt, Leigh-Anne Pinnock, Sharon Rooney and Julie Hesmondhalgh. As a result, the show brings together a wide mix of entertainment backgrounds and public personalities.
The format of The Celebrity Traitors continues to build on its original success. Contestants must form alliances, question motives and survive eliminations while trying to complete group challenges. However, trust remains fragile throughout the competition. The first celebrity edition of the series proved highly successful. In fact, it reached peak UK audiences of over 15 million viewers during its finale. Therefore, expectations remain high for the upcoming season.
Additionally, the BBC reported strong overall viewing figures across the first series run. The programme became one of the most-watched television events of 2025, which increased anticipation for the new cast. Joanne McNally’s inclusion adds further attention to the line-up. Known for her stand-up comedy and podcast work, she joins a group that blends entertainment talent with public figures from across different industries.
The series will again take place in a remote Scottish castle setting. Consequently, contestants will face both mental pressure and social strategy challenges throughout the game. Production teams have expanded the format slightly for the new season. However, the core structure remains unchanged, focusing on deception, teamwork and elimination rounds.
The Celebrity Traitors returns with a larger and more varied cast. As filming begins, viewers now look ahead to another high-stakes competition filled with twists and unexpected outcomes.
