Jane Seymour and John Zambetti think their love is a "miracle".
The 75-year-old actress recently announced her engagement to the 78-year-old musician after three years of dating and the couple urged others to be "open" to finding love later in life, however challenging it may seem.
John told Fox News Digital: "I think you just have to be out there and be open to it. I mean, just don't be in a shell, just be open to it, because it's all out there.
"There's lovely people out there everywhere. I mean this is just kind of a miracle in my opinion."
Jane added: "In my opinion, too. It's a miracle.
"I love him. I cannot believe that I got lucky enough to find the perfect person at this time in my life. I was not available before, and he wasn't available before. So, you know, now is it, right now."
The Harry Wild actress credited their mutual interest in each other's lives and work as being key to their happiness.
She said: "He understands that I love what I do. I understand how much he loves what he does.
"And we're just equally supportive of one another, and it's great.
"I go off and make a movie, he is there with me. I turn around, and he's put out four albums. I'm like, what?
"We're just equally supportive of one another, and it's great.
"And then I've become his muse. So, now he's written some amazing songs."
It will be the fifth marriage for Jane, who was previously married to theatre director Michael Attenborough from 1971, author Geoffrey Planer from 1977 to 1978, business manager David Flynn from 1981 to 1992 and actor James Keach from 1993 to 2015.
She and her new fiancé John first went Instagram official with their relationship in October 2023, with the famous redhead saying at the time that she had “never been happier”.
Jane added to Hello! magazine: "I honestly never thought I would find a really committed, healthy, lovely, loving relationship at this time of my life.
“But I’m incredibly blessed that I have. I consider both of us so fortunate to have found each other at the time we have, because it wouldn’t have ever worked earlier.
“He had a different life — his world was medicine and touring, and mine was running around the world making movies. I think we met each other at exactly the right time."
