Felicity Kendal has said that she and her ex-husband have pondered remarrying - but that they cannot be bothered.
The Good Life star, 67, and director Michael Rudman, 75 - Kendal's second husband - were together for seven years after tying the knot in 1983.
Years after their marriage broke down, the pair, who have a son together, reunited in 1998.
The actress told Good Housekeeping magazine: "Michael and I talk about marriage and then we decide we can't be a**ed.
"I think marrying the same person twice looks like carelessness - that's the way we look at it!"
Asked what she had learnt about love, the actress replied: "It comes and goes," and she said of what draws and keeps individuals together: "Sex! (and) m ore sex!"
Felicity, who famously played Barbara Good in 1970s sitcom The Good Life, has previously told how she gave up Botox because it looks "silly" on women of a pensionable age.
Now she has told the magazine: "There is pressure in the movie business (to look a certain way), but I'm not in that.
"I haven't done fillers or Botox for ages. There comes a point where you have to match bits of you with the other bits, otherwise you get a terribly random situation.
"All that is off the cards now."
She added that while women had become empowered, they are still judged unfairly on their appearance.
"Women have become incredibly independent. We've really come a long way in almost every walk of life in the past 30 years, and society is more equal now. But we've still got this hang-up about what women look like," she said.
"I do it myself. There is still an obsession with women's looks, and that's never going to go, but we could be a little more generous."
Felicity said that thanks to yoga, Pilates and weights, she is "fitter and stronger now than I was 20 years ago, and I've never felt so good."
But she added: "I don't believe in guilt. I used to feel guilty: I should do more exercise, I shouldn't do this, I should do that... But now I just think, this is who I am, and give into it. There's a liberation in that.
"At my age, women get to a point where we don't make decisions to impress somebody else, but to please ourselves."
She said of getting the first of her two tattoos - a star on her foot - four years ago: "It was the opposite of trying to be younger and 'with it', it was about celebrating the fact you're not young any more, so you know what you want to do. It's something I did totally for myself."
