Amanda Abbington with her new man Jonathan
The lovebirds are currently enjoying a romantic holiday away together in Vienna.
Earlier this year, Amanda revealed that her split from ex-husband and Sherlock co-star Martin could have caused "irreparable damage" to their kids.
The pair split in 2016 after 16 years together and the actress feared that the domestic trauma may lead their two children – Joe, 15, and Grace, 12 – to drink and drugs.
Amanda spoke about the breakdown of her relationship to Martin and its effect on their kids and it was reported the actress said: "Im sure I’ve given them irreparable damage and they will be going to therapy because of me and Martin at some point."

Speaking on Instagram in a live session for the It’s OK mental health campaign, the actress explained that she wanted her kids to know that "there's nothing to be frightened of or ashamed of" no matter what they go through.
She has previously maintained that she has remained friends with the Sherlock star for the benefit of their kids.
The pair worked alongside each other on Sherlock and Martin had previously admitted filming was "no fun" during the couple's split.
However, Amanda confessed that although she had "bad days," she wouldn't hide them from their kids.
She said: "To hide this for my children, that I get depressed and I’m on antidepressants, what are you saying about all these mental health issues?

"Are you saying they’re offensive and shouldn’t happen? I don’t want that."
The actress, who starred in Billie Piper's I Hate Suzie, also revealed how distressing it was for her son to read death threats made to her online.
She admitted that it's easy for someone to make an anonymous account online to troll people and to "destroy people".
"If I hadn’t been in a stronger place when I was getting those tweets all the time, I don’t know what I’d have done," the Safe star said.
The Mirror has contacted Amanda's representative for a comment.
