Jane Fonda recently admitted that she loves pornographic novels.

The 80-year-old actress is a big fan of erotic fiction and though she thinks E.L. James' infamous "Fifty Shades of Grey" was "not a very good book", she is "glad" it was written because it gave satisfaction to so many women.

Speaking on the High Heels and Hangovers podcast, she said: "I've read really good pornography. I lived in France for years and I read it when it first came out because I wanted to see what all the fuss was about.

"['Fifty Shades'] is not a very good book but I'm glad it was written and I think it titillated and juicified a lot of women in the United States. That's a good thing."

Jane - whose new movie 'Book Club' is about four older women whose love lives are given a boost by the raunchy novel - recently admitted she thinks sex gets better for women as they get older.

She said: "For women it gets better because we understand our bodies more. We know what we need and we know what we like and we're less afraid to ask for it."

The 'Barbarella' actress has also come to realise that sex and love are totally different things but they can be mindblowing when they both come together in one relationship.

She said: "You can have sex without love and you can have love without sex."

Her frisky talk came less than a year after she admitted that she had "closed up shop down there" because she's not interested in dating anymore following three failed marriages and three grown-up children; Vanessa, Mary and Troy. 

She said at the time: "I'm not dating any more, but I did up until a couple of years ago. I'm 80, I've closed up shop down there!"

These days, Jane lives in a house within a gated retirement compound, which boasts a community centre with a pool and tennis courts and though she never expected to dwell in such a facility, she adores her life there.

She said: "I always see one or two other residents who seem infinitely older than I am, but they probably aren't. I never thought I would ever live there, but it's great."
