Ioan Gruffudd has called in police after a woman claimed she was tricked into believing she was having an affair with him.

The Fantastic Four star - who has been married to Bianca Wallace since 2025 - has taken to social media to issue a warning after he discovered a female fan was allegedly duped into thinking she was involved in an "extramarital relationship" with the actor and he described the situation "incredibly distressing and disturbing".

In a post on Instagram, Ioan explained: "Something incredibly distressing and disturbing has been brought to my attention.

"A woman came to a convention I was recently attending and she was under the impression that she was in an extramarital relationship with me for over a year.

"She showed me hundreds of AI images and videos that someone claiming to be me had sent to her. The images were explicit and disturbing. "

Gruffudd explained the woman was initially targeted through a Facebook fan page for one of his films and the alleged scammer then used social media platform Telegram to communicate with her.

The actor added: "They began sending Al images and videos to 'prove' that it was me. If you believe you are speaking to me via message, Telegram, any social media pages that aren't this page (@ioangruffudd) or any other means, this is not me.

"I will never give out my cell number to anyone that I don't personally know. Please do not engage and never send money! I urge you to ignore and block all contact from anyone that claims to be me."

He went on to urge anyone who thinks they may have been targeted to contact police, adding: "Lastly, if you have been targeted by this person, please report them to the police for investigation. I have done the same."

In a separate post, the actor added: "I'd like to make an important clarification - this has not been a financial scam. No funds ever requested from her or sent by her.

"This person has specifically targeted the victim/s to create a false relationship. I clarify this as this as the victim specifically stated that this was the reason why she never questioned it and what made her believe that this was truly me. Please be careful out there."
