Woods is said to have listed all the women he was involved with behind his wife's back as part of his treatment for sex addiction but failed to include one woman - his neighbour's 21-year-old daughter.
The National Enquirer claims it was this omission that finally caused his wife to pursue a divorce.
According to the Enquirer, the mother-of-two made the decision after learning the publication was investigating Woods' alleged fling with Raychel Coudriet, whom he had reportedly known since she was just 14.
After learning of the alleged one night stand, it's claimed a furious Nordegren phoned Woods after his comeback at this year's US Masters.
"She was screaming so loudly that everyone at the table could hear what she was saying," a source was quoted as saying.
