Claudia Winkleman has claimed she is "too thick" to ever compete on Celebrity Traitors.
The television host returns to screens on Thursday as a fresh group of famous faces enter the Scottish castle.
Actors Michael Sheen and Richard E Grant, supermodel Jerry Hall, presenter Maya Jama and comedians Rob Beckett, Romesh Ranganathan and James Acaster feature in the lineup, alongside Little Mix singer Leigh-Anne Pinnock, musician James Blunt and The Last of Us star Bella Ramsey.
However, Winkleman insisted she would never join the contestant line-up herself.
She said: "I’m too thick. I mustn’t play it in public. I must not, thank you so much. I’m just being honest. I could have come up with a schmoozier (answer) but no.
"It’s a privilege to play that game and to be at the round table, but I think I would just be too awful at it."
The show follows the celebrity players – the majority of whom are designated as faithfuls – as they attempt to uncover the murderous traitors hidden among them, who eliminate contestants during the night.
The inaugural celebrity series was won by traitor Alan Carr, proving a major broadcast hit and picking up numerous awards.
Executive producer Sarah Fay said she was "chuffed" with the initial response and expressed hope that the second instalment lives up to previous achievements while upping the ante.
She said: "We never take for granted that the audience is always going to come to it.
"So (the first series) felt a little bit like Monopoly money, it just didn’t seem real, but obviously we’re so, so chuffed."
She continued: "But going into the series, we wanted to make sure it felt it wasn’t comparable and we could bring a new freshness to it.
"A new cast could bring something to it, whether that’s the dynamics of Rob and Romesh, with a celebrity duo with new twists, new turns.
"We’re always looking at ways to up the ante and make it feel like compelling viewing."
The Celebrity Traitors begins on Thursday October 1 at 8pm on BBC One and iPlayer.
