She is best known for her series of raunchy romance novels known as "Bonkbusters".
But it seems that Jilly Cooper's own diaries are more racy than her fiction, as she told her kids to burn them after she died.
The 83-year-old writer hopes her children Felix and Emily destroy the detailed diaries she has kept since the early 1970s, as she does not want to embarrass them.
Also, Miss Cooper, who has been single since husband Leo's death in 2013, doesn't want to speak publicly about the racy parts of her love life.
When asked about rumors that the couple shared their bed with other people in the 1960s, she told Sunday Times Magazine, "I don't want to talk about it … my kids wouldn't like it.
Jilly Cooper (pictured last January) has admitted she never cried over her husband's death and was "closed" on his six-year affair after offering condolences to his ex-lover when he died
“I mean, it was very busy back then. The sixties – they were very different. & # 39;
From her diaries, she said, "I say to my children, you know darlings, I don't want to embarrass you, and so I think they should be burned … They are pretty, good, quite classy."
also admitted that she never cried over her husband's death and was "closed" on his six-year affair after offering condolences to his ex-lover when he died.
The best-selling author, 83, known for her classy readings including Riders, Rivals and Polo, lost Leo, with whom she shared two adopted children, in 2013 at the age of 79 after a long battle with Parkinson's disease.
She also said she never cried over her husband, who was 52 years old, adding, “I haven't cried about anything in ages. I don't cry anymore. & # 39;
She added that she has been screened at her Cotswolds home since the lockdown began and has barely left the house in six months – but insisted that she is not lonely and has no desire to meet anyone else.
When it was discovered that Leo was having an affair with Sarah Johnson, a publisher who spilled the beans in the Guardian, Jilly said it was "crucifixion" – but they managed to work it through and keep their marriage alive.
After he died, Jilly told a friend of Sarah's to give her my love and added, I hope she is not too sad.
The writer later received a card that said, 'Dear Jilly, thank you' and admitted that it was' closed ', adding,' Falling in love with someone who then stays with their wife must be very irritating , may not it? & # 39;
The writer herself was not faithful throughout her marriage and previously shared how her own behavior helped her forgive Leo's betrayal.
& # 39; In the early days of our marriage, I fell madly in love with someone else and had an affair. After that, Leo just opened his arms and said, "Come back," she previously told the Daily Mail.
When it was discovered that Leo (pictured with Jilly in 2001) was having an affair with Sarah Johnson, a publisher who spilled the beans in the Guardian, Jilly said it was "crucifying" – but they managed to work it through and keep their marriage alive
“He was wonderfully forgiving and now everyone is beating him up for misbehaving. But an affair can happen to anyone. I don't think it's a reason to break up a marriage. And nobody really has any idea what happens between a couple when the door is closed, do they?
"Often times, when a husband or wife is slandered for bad behavior, the other half has behaved far worse."
Speaking to the Sunday Times magazine, she found that she suspected that Leo always struggled with the fact that her literary career was more famous than his – as an editor of books on military history – more than he allowed it to be .
"For a man to be married to a woman who is very successful in public, it has to be very difficult," she said.
Jilly also turned down the idea of meeting a new man, telling the publication, "I can't imagine anyone wanting to go to bed with you anymore. You know what I mean?"
Speaking of the current lockdown restrictions, she quipped, “If I were 21 today … I'd probably break the rules. It would be terrible not to be able to kiss a handsome young man. & # 39;
She joked that the only "good thing" about the coronavirus pandemic is the fact that "everyone has put on a little weight," adding, "When nice men come to your home, they can't hug and feel you."
