The Crown star Emma Corrin was spotted watching the tense Wrexham vs Notts County game with a male friend by their side.
The actor, 27, was spotted sitting in the stands watching the game on bank holiday Monday, sporting a black baseball cap.
Sitting next to a male friend, Corrin cheered on Wrexham along with its famous co-owners, US actors Ryan Reynolds and Rob McElhenney.
Earlier this year, it was confirmed that Corrin – who shot to fame playing a young Princess Diana in Neflix drama The Crown – would be joining the Deadpool franchise.
Reynolds, 46, who plays the foul-mouthed anti-hero Deadpool, wrote on social media: “New addition to the family! The Deadpool family, for clarity. Which is just like a real family except with less swearing... Welcome, Emma Corrin!”
It comes as Reynolds said it is “troubling” how “hooked” he is on football after watching his team beat Notts County.
The Hollywood actor said the drama of the match was “unlike anything you’ve ever seen in a damn movie” – and did not quite know how to quantify what he had seen.
Wrexham struck a potentially decisive blow in the Vanarama National League title race with a 3-2 victory over their rivals on Monday, after former England goalkeeper Ben Foster saved a stoppage-time penalty.
Footage from the match showed Reynolds and fellow actor McElhenney, with whom he owns the club, celebrating wildly after the save.
Speaking to BT Sport in the aftermath, the Deadpool star praised the “inner strength” of the players on both sides.
“I don’t feel like I have a heart any more. I think I used all the beats that I had left during that match,” he said.
“That was unlike anything I’ve ever seen before and indicative, of course, of all of you lifers who have watched and participated in this game, this beautiful torturous game, for forever.”
He continued: “I’m actually grateful in this moment that I didn’t care about this years ago because it would have just eaten me alive.
“I’m very hooked. It’s troubling how hooked I am. I’m usually not at a loss for words but I’m genuinely at a loss for words in this moment. I don’t quite know how to quantify what just happened.”
Reynolds added: “I’m used to working under extreme pressure but usually I have some kind of say in it; I have some control over it.
“I have nothing here. All I can do is watch and hope like everybody else.
“It was a pressure cooker coming into this, I think, for both of these teams. What both have achieved is historic on every level and, you know, I don’t think I’ve ever seen anything quite like that.”
Reynolds then joked that star of the match Foster was going to be on the “injured reserve list” for upcoming games.
“I’m going to break ribs, I’m going to hug him so hard,” he said.
Reynolds and McElhenney have been widely praised for their investment and involvement in the club since completing a deal for its takeover two years ago.
The pair have raised the profile of the club and city of Wrexham through fly-on-the-wall documentary Welcome To Wrexham, and have been honoured by the Welsh Government for helping to promote the Welsh language and culture.
