Jane Seymour and her partner think it is "safer" to celebrate their anniversary every month

Jane told Briain's HELLO! magazine: "Today is our 25th anniversary - 25 months today.

"We decided that [because] we met in our seventies it's probably safer to go every month. So every month, on the fourth, he sends me roses, wherever I am, whatever's going on. We're just so grateful for every minute we have together."

Jane - who was married four times before she met John - feels "so fortunate" that she and her partner, who is also a musician, met so much later in life because she doesn't think things would have worked out between them otherwise.

She said: "You've had a life. Many lives. And children, and grandchildren, and careers, and ups and downs. You know what you want. 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."

The Harry Wild actress admitted that sex is still important in their relationship.

She said: "In my parents' generation, and I think a lot of people, they reach a certain age and they go, 'That's not part of our life any more, and it's not necessary'. I just think, with maturity, you understand your body, you understand what feels good and you have knowledge, so put it down to that."

Jane couldn't be happier with her life today.

She said: "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. 70 is the new 50...

"To have life and to have the world that we live in, and to have my grandchildren and friends and work that I love, and a man that I love. That combination gives me joy."
