Actress/model Jenny McCarthy is planning to write a new cheating study.
The star, who is dating funnyman Jim Carrey, has launched a campaign to gather fans' infidelity stories via her blog.
The research will be used for MCCarthy's new tome, which she insists is a "look inside love and sex".
In launching the research bid, MCCarthy asked her female fans, "How many girls have fantasised about being with another girl?"
