In real life, the actor has been married to Irish landscape designer and aristocrat Catherine since 2010, who he has four children with.
A female friend of Catherine who reportedly came to console her at the family home near Chippenham, Wiltshire, told the Daily Mail that she has seen the pictures and is "devastated" as she thought they were "very much together" with a "good marriage".
"Catherine has seen the pictures and she's devastated. I came over to speak with her as soon as I knew about them," she said.
"Catherine has been trying to speak with Dominic but he's not answering his phone. She's totally shocked because she didn't know anything was going on. They were very much together, so this is completely out of the blue."
"She thought they had a good marriage and now it's probably over. That's how she feels right now but the two of them need to speak but at the moment, she's lost for words."
Earlier this week it was confirmed James had split up with her boyfriend Matt Smith after a failed attempt to rekindle their relationship in lockdown following an on-off five-year romance.
