All The Stars Rumoured For Celebrity Traitors UK Series 2

While the confetti has barely settled on the epic finale of Series 4, which saw traitors Rachel and Stephen bag the best part of £50,000 each, speculation has already been running wild over who might return to Ardross Castle for a second series of The Celebrity Traitors…

Season one of the BBC’s high-stakes, celebrity spin-off of the hit reality game show captured the nation’s imagination, as the unique blend of social strategy, alliance-building drama, and all-out deception, was matched with a whole host of houselhold names. And with the second season officially confirmed for 2026, speculation around its star-studded cast has reached fever pitch.

While no official lineup has been released as yet, a slew of names have been floated by bookmakers, TV insiders, and entertainment news outlets. So, here’s a rundown of the biggest celebrities rumoured to be stepping through the castle doors this year - and why we’re excited about each of them.

Danny Dyer - EastEnders Icon Turned Traitor?

One of the most talked-about names in the rumour mill is Danny Dyer, the beloved EastEnders actor. According to reports, Dyer initially turned down a place on the first series, but has since warmed to the idea after watching the show’s success. If he signs up, he’s expected to bring his trademark blend of charisma and drama to the castle, and could be either a loyal Faithful or intimidating Traitor.

Alison Hammond - Reality TV Royalty

TV presenter and national favourite Alison Hammond is another big name said to be in talks with BBC producers. With her infectious humour and candid personality, many fans think she’d be a perfect fit for the Traitors format whether she’s building trust as a Faithful or ruthlessly scheming as a Traitor.

Daisy May Cooper - The Comedic Wild Card

Comedy star Daisy May Cooper, best known for This Country, is believed to be in discussions with the show’s team after initially being linked to the first series but forced to pull out due to family commitments. Now, with her comedic flair and sharp wit, she’s considered a prime rumoured candidate for Series 2 and would be someone who could shake up the group dynamics in unforgettable ways.

Ruth Jones - Gavin & Stacey’s Finest

Ruth Jones, the beloved Gavin & Stacey co-creator and star, is another actor tipped to make an appearance. Insiders say producers have been approaching her for the new season because of her warmth, intelligence, and household recognition, qualities that would translate well to the intense social gameplay of Traitors.

Tom Hiddleston - Hollywood A-Lister With A Taste For Games

Perhaps the most surprising rumour yet is that Tom Hiddleston, the Thor, Loki and Night Manager star, has publicly admitted he’d love to take part in Celebrity Traitors. Speaking on BBC Radio, Hiddleston described the format as ‘ingenious’ and hinted he’d be intrigued by the psychological challenge it presents, whether as a Faithful or a master manipulator…

Steve Pemberton - ‘Big Dog’ Contender

Award-winning actor and Inside No. 9 co-creator Steve Pemberton has also been named as a potential lead character (or ‘big dog’) for the upcoming series. With a reputation for nuanced performance and puzzle-loving intelligence, Pemberton is thought to be highly sought after by producers, potentially filling the kind of strategic role that Jonathan Ross embodied in the first series.

Other Stars on the Radar

Beyond the major rumoured names above, a wider list of potential contestants continues to circle the gossip columns:

• Amanda Holden - tipped by insiders and even encouraged by Alan Carr to take part despite busy commitments.

• Gareth Southgate - the former England manager has featured in casting speculation.

• Bob Mortimer, Davina McCall, Lily Allen, Olly Alexander, Greg James and even Mike Tindall have all been named in entertainment betting lists circulated online.

Although the official cast list for Celebrity Traitors UK Series 2 remains under wraps, the rumours alone have sparked incredible anticipation. From actors to broadcasters, from reality stars to Hollywood names, the range of potential contestants showcases just how seriously the BBC is approaching this new season. Fans can expect more strategic gameplay, bigger personalities, and even higher drama when the doors to Ardross Castle open again later this year.

Whether these rumours come true or not, one thing’s certain: Series 2 is shaping up to be television gold!
