Opening up about being married to another actor, Nicola told HELLO!: "The great thing is my husband came from his mum and dad are both actors, so he had a healthy disregard for acting. He sort of saw the business for what it was, which was always really nice.  

"If you're with someone who's an actor, the great thing is you don't have to talk about it because they know how your day's been. You fall in love with the person, not what they do, don't you? He's a great person."

Nicola and Barnaby's relationship 

Nicola and Barnaby tied the knot after 20 years together in 2006, which was the same year they welcomed their son, Harry. 

Opening up about her nuptials during an interview with the Radio Times in 2018, Nicola revealed the couple had a "tiny, family" wedding. "I don't know if I should tell the truth – it doesn't sound very romantic," she began. "I find the whole ceremony of marriage a bit like going to work. It's a public performance. Though we had a really lovely day because we didn't do that. We had a tiny family thing."

In a 2022 interview with the publication, Nicola went on to explain that she and Barnaby decided to marry for one reason in particular. "Me and my husband, because we both lost a parent young, we thought, after we had a child, we ought to get married, in case one of us dies, so that the legalities are clear," she said. "Which is not the most romantic reason to get married but is probably the only thing that would have got me to sign a piece of paper. I’m not a great advocate of marriage in real life."

Nicola's son Harry 

Nicola and Barnaby share a 19-year-old son called Harry, who is currently studying at university. 

While Nicola tends to keep her son Harry out of the spotlight, she has previously shared an insight into their family life. Speaking to The Mirror in 2022, the Annika actress revealed that her son hasn't watched any of her work in full, although her husband is "very supportive". "I don't think my son has ever seen anything I've done," she told The Mirror. "He's seen bits but he's never watched a whole episode, because obviously that's weird, as I'm his mum."

She added: "My husband, Barney, watches it though. He's very supportive."

In a recent interview with The Times, Nicola revealed that Harry is in his last year at school and is busy choosing universities. Sharing her apprehension about becoming an empty-nester, she said: "I'm clinging to him like an annoying marmoset. The poor young man is like, 'Back off!'"
