She created the world's most famous singleton - and Bridget Jones author Helen Fielding's research suggests women should try being "really horrible" to become lucky in love.
Fielding revealed she set up fake profiles on dating websites at an event in Los Angeles where she was speaking about her latest book in the series, Mad About The Boy, the Mail on Sunday reported.
As part of her research, the author created an account featuring a photograph of a woman in a sensible jumper who loved to read and cook, and a separate account for a woman called 'SuperLuckyBitch' who had a sexy photograph.
"So I had SuperLuckyBitch who was glamorous but really horrible and it said on her profile, 'You'd be lucky to get a date with me', and the other woman was really nice and sweet.
"Well, I bet you can guess who was the most popular.
"SuperLuckyBitch got all the replies," she said, according to the newspaper.
Fielding admitted to meeting up with one man she met online through her fake profiles.
"I went and met him and explained I was doing research and he was very nice about it," she said.
During the 90-minute talk, Fielding also discussed similarities between herself and Bridget, including their obsessive streaks and disorganised approach to work, the newspaper said.
The author said she would not write another Bridget Jones book "just for the sake of doing it", but only if she had "something to say".
Fans were shocked and upset to learn that hero Mark Darcy is dead and Bridget has become a widow in the latest book.
More than a decade after the last novel in the saga, it turns out unlucky-in-love Bridget married Darcy and gave him two children - only for Fielding to kill off the awkward yet successful barrister.
Heralding the arrival of ''chick lit'', Bridget Jones's Diary started life as as a newspaper column in 1995.
Two best-selling novels followed, with Hollywood blockbuster film adaptations featuring Renee Zellweger as Bridget and Colin Firth as Darcy.
Portrayed as a stereotypical 1990s London thirty-something worried about her weight, smoking and alcohol intake, Bridget struck a chord with women of her generation.
The modern-day heroine's story - loosely based on Jane Austen's Pride and Prejudice - was centred around love interests Darcy and her cad boss Daniel Cleaver.
After hearing from her last in 1999 with Bridget Jones: The Edge of Reason, readers now find Bridget as a 51-year-old widow obsessed with wrinkles.
Fielding, who has always denied that the books are autobiographical, is herself a 55-year-old single mother-of-two who ended her relationship with television executive Kevin Curran in 2009.
Bridget's new adventures as a 50-something cougar sees her meet new 30-year-old toy boy boyfriend, Roxter, on Twitter, five years after Darcy's death.
