Comedians James Acaster and Mel Giedroyc are among the 21 famous faces confirmed for the second series of The Celebrity Traitors, set to air on BBC One and iPlayer later this year. Host Claudia Winkleman will welcome the eclectic cast to the Traitors castle, where they will compete for a cash prize of up to £100,000 for their chosen charities.
The line-up also includes BAFTA and BRIT award winners, social media stars, and beloved actors, presenters, and comedians. The show, produced by Studio Lambert Scotland, challenges celebrities to navigate deception and betrayal in the ultimate game of trust.
Series one of The Celebrity Traitors debuted in October 2025 and became a runaway success, averaging 14.9 million viewers across its run, with a peak of 15.4 million for the finale. It was the top entertainment episode across the market since 2016 and the number one series across all genres and platforms in 2025.
The fourth series of the original The Traitors, which aired in January 2026, also performed strongly, achieving a 12.5 million 28-day average—up 22% on series three. BBC iPlayer drove 53% of viewing for that series.
The Celebrity Traitors series two (10 x 60 minutes) is commissioned by Kalpna Patel-Knight, Head of Entertainment Commissioning for the BBC, with executive producers Mike Cotton, Sarah Fay, Lewis Thurlow, and Katy Fox. The show is set to return later in 2026.
