During a live recording of The Rest Is Entertainment podcast, broadcaster Richard Osman seemingly let slip the launch date for the second series of The Celebrity Traitors. The 55-year-old host confirmed the date as September 23 during a conversation with co-host Marina Hyde and special guest Joe Marler, a former contestant on the show. Marler had asked, “What is it, September 23, the next series?” to which Osman replied, “By the way, to point out, it’s absolutely embargoed that it starts on September 23 … let’s talk about what we call the events of September 23 this year … the cat’s out of the bag, isn’t it? Not to repeat it.” An embargo is a restriction on when information can be shared publicly, so Osman’s comment suggests he was not supposed to reveal the date. The upcoming series of The Celebrity Traitors will feature 21 new celebrities competing for a cash prize of up to £100,000, which they can donate to a charity of their choice. The game will take place in a Scottish castle in the Highlands, where contestants known as "faithfuls" must identify the "traitors" among them—players who eliminate others overnight. The first series, which aired last autumn, was a huge success, drawing a peak audience of 15.4 million viewers and featuring a finale that became the most-watched television broadcast of 2025. According to one report, the new series will be more intense than the first, with contestants appearing more competitive and focused on winning. Joe Marler noted that the atmosphere this time around was different, with participants seeming more driven to succeed than just have fun. He also suggested that the success of the first series may have created some pressure on the new contestants to perform well. The new cast includes well-known names such as Michael Sheen, Maya Jama, Bella Ramsey, James Blunt, and Leigh-Anne Pinnock. The BBC has not officially confirmed the launch date, but a new teaser trailer has been released. The second series of The Celebrity Traitors is expected to premiere on BBC One and iPlayer later this year. The BBC has been contacted for comment.
