FANS of The Celebrity Traitors have been left convinced that there are THREE more celebrities yet to be unveiled ahead of the first series. The Sun exclusively revealed ALL of the stars heading to the Scottish castle last month with the BBC now issuing their first official portraits of the stars in action. The line-up is mostly comprised of stars who have never delved into the world of reality TV before albeit for one or two exceptions. Stephen Fry, Tom Daley, Clare Balding, Paloma Faith and Kate Garraway lead the line-up of contestants but some fans think there are still more to come. The Sun confirmed the 19 celebrities who would be entering the castle on Day 1 but eagle-eyed fans have insisted there needs to be 22 players for the show and have speculated they could arrive later on into the game. Moreover, they think they have also worked out the stars hiding in plain sight from the line-up. One star that fans think could be making an appearance is comedian, Bob Mortimer. The TV favourite was heavily rumoured to be taking part in the show but when his name failed to materialise on the line-up, fans have now been left convinced he could rock up as a later arrival. Writing on Reddit, one fan said: "I wouldn't be surprised if someone like Bob Mortimer was introduced late on, once the others have arrived at the castle." As another echoed: "They should just chuck him a wild card, so nobody actually knows what he's doing!" Elsewhere, fans think that The Traitors spin-off show host Ed Gamble could also be taking part in the game. The comedian took a mystery two-week break from his Radio X show for the exact same weeks that filming for the reality TV show took place in Scotland sparking some speculation he could secretly be a part of the cast. One theorised: "I have very strong suspicions that Ed Gamble is the missing cast member." As another jumped in to point out: "He's was missing from his Radio X show for 2 weeks with no mention of holidays (which is usually a big topic) and just some vague mention of "doing another thing'. So Traitors was my first thought. "He was mysteriously absent the last week of April and first week of May and then back doing the show on Sunday 11th. They had a planned stand in trailed in advance so it wasn't like a sudden illness either." Whilst another name suggested is RuPaul's Drag Race UK star Tayce. Fans were left surprised to see the BBC competition show's stars had seemingly been snubbed from the programme but could last year's Strictly Xmas special winner Tayce be entering the castle late? One fan quipped before suggesting Tayce: "[The] Lack of UK Drag Race queens is disappointing." The 19 stars who will be starting the show are formed of actor Stephen Fry, comedian Alan Carr, Ted Lasso star Nick Mohammed, Olympian Tom Daley and rugby ace, Joe Marler. They will be joined by historian David Olusoga, YouTube star Niko Omilana, Line of Duty actor Mark Bonner, talk show host Jonathan Ross and comedian Joe Wilkinson. TV presenter Clare Balding, comedy star Lucy Beaumont, Brit Award-winning singer Paloma Faith, Netflix actress Ruth Codd and EastEnders legend Tameka Empson will also be hoping to win the £100,000 cash prize for charity. Completing the line-up are legendary actress Celia Imrie, singer Charlotte Church, Good Morning Britain host Kate Garraway and popstar, Cat Burns.
