Sir Stephen Fry, Alan Carr, Paloma Faith, Charlotte Church and Jonathan Ross are among the stars who will pit their wits against each other after being confirmed on the line-up for the celebrity version of hit TV show The Traitors.
A total of 19 presenters, actors, singers, comedians and sportsmen will attempt to be good traitors and faithfuls in the show, which will air this autumn.
The line-up - one of the most star-studded in reality TV history - will also include Clare Balding, Kate Garraway, Celia Imrie and Nick Mohammed.
Olympic champion Tom Daley and long-serving England rugby union player Joe Marler will bring their sporting strategies to the Traitors castle in Scotland.
Host Claudia Winkleman said: "We're incredibly lucky these brilliant people have said yes. I'd love to say we'll take it easy on them and they'll just wander round the castle and eat toast for a couple of weeks but that would be a lie."
The participants will be seen competing for up to £100,000 for a charity of their choice.
It is the first celebrity version of the show, and will consist of nine hour-long episodes.
The latest regular series was broadccast in January, attracting more than 10 million viewers per episode.
