She said after welcoming James: ''Everything takes on a new meaning. It took a long time to get pregnant--for me the baby was such a blessing that the most important thing for me was that I was active.

''I was never obsessive about dieting or exercise. I didn't care how much I gained. I just wanted to make sure he was healthy.''

The blonde beauty had previously been diagnosed with endometriosis as well as polycystic ovary syndrome, a condition that affects female sex hormones and fertility, after a number of failed and painful treatments of IVF.
