Season three of The Traitors is nearly finished, with the grand final being held on Friday, January 24.

Millions of viewers will finally find out who will triumph - and whether it will be a Traitor or a Faithful that wins the prize of over £100,000.

Fans will then face a long wait for season four to arrive in early 2026, with casting currently taking place.

But, for those needing an extra fix of gameshow intrigue, season three of the American version presented by Scotland’s own Alan Cumming, is on its way to the BBC.

Cumming won an Emmy for his dramatic hosting of the show that, unlike the UK version, fills the castle with celebrities.

It should be noted though that only a couple are likely to be familiar to Brits as most are famous for reality television programmes not broadcast here.

Here's everything you need to know - including that cast.

Who is appearing in season three of The Traitors US?

Here are the 21 celebrities who hae been confirmed to take part in season three:

• Rob Mariano (Survivor)
• Dorinda Medley (The Real Housewives of New York City)
• Chrishell Stause (Selling Sunset)
• Britney Haynes (Big Brother)
• Danielle Reyes (Big Brother)
• Bob the Drag Queen (RuPaul’s Drag Race)

What are the rules?

The contestants live together in a castle and work together to take on tasks to add cash to the prize pot – up to $250,000.

The complicated bit is that three of the contestants are secret Traitors, who are trying to elimiate the remaining ‘Faithful’ players to bag the money for themselves.

Each night The Traitors meet in secret to pick one of The Faithful to ‘murder’, with that contestant leaving the game immediately. The following day all the players meet around a round table to banish somebody they think is one of The Traitors – who then reveals which side they actually belong to.

At the end of the game, if only The Faithful remain they will share the money in the prize money. If one of The Traitors remains, that person will claim all the cash.

Where is The Traitors US filmed?

The Traitors US is filmed in the same castle that hosted the UK version – at Ardross Castle, situated in the Highland region of Scotland near the River Alness. Ardross Castle was originally a hunting lodge for the 1st Duke of Sutherland in the late 1700s.

In the 1880s, the lodge was redesigned as a castle in the period’s baronial style. Nowadays, it is used as a wedding and conference venue.

Who is hosting?

Scottish actor Alan Cumming is once again taking on the role played by Claudia Winkleman in the UK version of The Traitors.

Cumming first found fame in the role of the MC in the stage musical Cabaret, first in London’s West End and then in Broadway. Since then he has starred in a slew of successful television programmes and feature films, including The High Life, The Good Wife, Goldeneye, Spy Kids and X-Men 2.

He also continues to appear on stage, most recently appearing in one-man show 'Alan Cumming is not Acting His Age', which toured Scotland last year.

What has Alan Cumming said about Season 3 of The Traitors US?

Speaking to American actress Laverne Cox at the Emmys, Cumming spoke about season 3 of The Traitors US, explaining "It's brutal. Big time brutal - and what I love about this is that some of the people, like the biggest set of stars in it, go out really quickly. And what happens on this, I can't really say, of course, but it's a bloodbath, and then it gets really lovely."
