Danielle Lloyd recently revealed that she is expecting a baby girl after using a controversial sex-selection guide called The Babydust Method.
The mum-of-four shares Archie, 10, Harry, nine, and George, seven, with her ex-husband, footballer Jamie O’Hara, and Ronnie, three, with current husband Michael O'Neill.
She came across the guide, written and researched by Kathryn Taylor - who has a degree in Microbiology, Immunology, and Molecular Genetics from UCLA - and followed it in hopes of having a girl.
Danielle revealed she followed the book “to a T”, explaining to OK! magazine : "I tried it previously and I got pregnant but I had a miscarriage. So this time I was trying for a few months and nothing happened.
"When I got the negative result I felt really upset about it and Michael said, 'Come on, let’s leave trying now and do the gender selection.'
"I had come to terms with the fact that we weren’t going to try any more and then two or three days later I found out I was pregnant."
The author, Kathryn, based her Babydust Method after Missionary Sister Dr Léonie McSweeney's 2011 study.
99 couples in Nigeria monitored their ovulation and then had intercourse with the exact timing and number of times placed depending on what sex they wanted their child to be.
For families that wanted a girl, sex could only happen only once, exactly two to three days before ovulation.
And if the couple wanted a boy, intercourse was meant to happen twice, as close to ovulation as possible.
Women chart their luteinising hormone twice a day and use ovulation predictor kits for three months before they want to conceive a child so that they could recognise patterns in their cycle.
The luteinising hormone surges at around day 14 in the menstrual cycle and ovulation, which is when an egg is released from the ovary.
Kathryn had taken to her Facebook to warn followers that she isn't a doctor but simply wanted to help people better understand the method.
She explained: "I have to mention, I am not a doctor, and I cannot guarantee you'll conceive the sex of your choice.
"All I can do is help you better understand how to implement the method, and give you encouragement along the way."

Doctors have been sceptical about the method, explaining how the chances of getting a boy or girl are usually 50-50.
"There are some scientific ideas on how to improve your chances to get a boy and girl," Dr. Elena Trukhacheva, President and Medical Director of Reproductive Medicine Institute in Chicago, Ill., told Refinery29.
"But in real life, it’s 50-50. These ideas are not going to take you farther than 50-50, and it’s not going to work for some couples."
It is important to note that no exact method can promise the desired results.
