Helena Bonham Carter, 60, and her 'old-soul' lover Rye Dag Holmboe, 38, walk their dogs as they enjoy a romantic stroll

They've been inseparable since first being linked in October 2018.

And Helena Bonham Carter and her 'old-soul' lover, Rye Dag Holmboe, looked the picture of domestic bliss as they enjoyed a romantic dog stroll in Hampstead, north London, on Tuesday.

For the occasion, the actress, 60, showed off her unique sense of style in a grey blouse and red trousers adorned with a lace-trimmed hem.

She wrapped a pink jumper around her waist and placed two pairs of glasses on her head. 

Meanwhile, Rye opted for a blue shirt and trousers with a green jumper tied around his neck. 

Although they appeared happier than ever, Sweeney Todd star Helena previously explained she will never tie the knot because she can't make an 'unhealthy' promise to be with someone forever.

Speaking about her relationship with Rye in December, Helena confessed: 'I mean, we're not meant to be forever.

'And I've never actually gotten married because I can't say those [words], I can't honestly make that promise because I just don't think it's a healthy one.'

The smitten couple first locked eyes at a wedding both of them almost didn't attend.

She told The Guardian of their meeting: 'A totally random thing, which both of us nearly didn't go to, so it was one of those moments that was so chance and ended up determining so much.

'A really happy accident, and it's an amazing thing. I can't say much about Rye, because he's a psychoanalyst, so he needs his anonymity.'

The couple went public with their romance the following year, five years after she split from her long-term partner, director Tim, 68.

The actress had admitted it was time to find love again when she realised she was 'bored' of grieving her former relationship.

She told Harper's Bazaar: 'You break up, you grieve, you get bored of grieving. And then you finally move on.'

Speaking of Rye, she added: 'I'm very happy with someone else. It's been a bit of unexpected magic in my life.'

Addressing the couple's 21-year age gap, the actress previously said in an interview with The Times: 'Everybody ages at a different rate. My boyfriend is unbelievably mature. He's an old soul in a young body, what more could I want?

'People are slightly frightened of older women, but he isn't. Women can be very powerful when they're older.'

She added: 'There are people I've been involved with who aren't necessarily their age, maturity wise, whereas [Rye] is ageless.'

The actress split from her long-term partner, director Tim, in 2014. The pair have two children, Billy, 23, and Nell, 18.
