An actor, who starred in Game of Thrones, said he was shocked to see his Lancashire mum on the new series of BBC reality show The Traitors

Kerr Logan, who grew up in Lytham St Annes according to acting profile, appeared not to know that his mum Diane was set to appear on the show until pictures emerged of the cast on January 2.

He said: “A family member of mine is in this photo and I’ve only just found out.”

In a later tweet Kerr, who starred as Matthos Seaworth in Game of Thrones, confirmed that Diane was is mum adding that she is “bonkers”.

Sharing a picture of her he said: “My mother is on The Traitors. She’s bonkers. I’m scared.”

Kerr, who also appeared in Alias Grace and London Irish, said: “My mother is trending on twitter... one of the more surreal nights of my life.”

The show only started on Wednesday night (January 3) but Diane has quickly become a fan favourite on social media.

Presenter Rylan Clark said: “Never been more afraid of being found out by [Diane] and I’m not even a traitor on the show

One fan wrote: “I would sell my limbs for Diane to be recruited [as a traitor] at some point.”

In this nail-biting psychological reality competition, Claudia Winkleman greets 22 strangers as they arrive at a beautiful castle in the Scottish Highlands to play the ultimate game of detection, backstabbing and trust, in the hope of winning up to £120,000.

But hidden amongst them are traitors whose job is to secretly murder a player every night, without getting caught.

It’s up to the others, the faithfuls, to try to detect who the traitors are, and banish them from the game, before they become their next victim.

For the lucky ones who survive to the end, they have the chance of winning that life-changing cash. But if a Traitor remains undetected, they’ll steal all the money.

Diane, a  63-year-old retired teacher, is one of three Lancashire contestants on the show.

Ross, a 28-year-old video director, is also said to hail from the county as well as Sonja, a 66-year-old volunteer business mentor.

You can watch The Traitors on BBC iPlayer. The next episode airs tonight (January 4) at 9pm, on BBC One.
