“Please avoid sharing potential spoilers so that the millions of fans who have been faithfully following every twist and turn of the series can enjoy the final this evening.”
The Celebrity Traitors is currently the most-watched TV show of the year, with an average of 12.6m people across the first four episodes.
Fans of the show have been waiting to see whether traitors Cat Burns and Alan Carr will win the £100,000 prize for charity or whether faithfuls Joe Marler, Nick Mohammed and David Olosuga will be triumphant.
Jake Brown, who was one of the winners of the third series of The Traitors earlier this year, told the BBC that “no one likes spoilers”, which are “the thief of joy”.
He said he will be sitting down to watch the final tonight live, with all of his family and “a bucket of popcorn”.
Thursday evening’s final episode is extended to 70 minutes on BBC One, with an extended edition of The Celebrity Traitors: Uncloaked set to air on BBC Two after the final.
Host Ed Gamble will be joined by the cast and Claudia Winkleman as they react to the show’s outcome.
