Selma Blair has revealed her body is still depleted after years of breastfeeding her son.

The 45-year-old actress is mother to six-year-old son Arthur - whose father is fashion designer Jason Bleick - and nursed the youngster for years to help with his medical issues, at the expense of her own health as she thinks it led to her becoming malnourished.

Selma told The Observer newspaper: "My son had some health issues and he really needed the breast milk, so that really was my job. I thought: 'Aaaah, I guess I can die now, I got him through that!' But I depleted myself, too, and I'm still recovering. I still have to remind myself that my own body needs healthier fats than fried food."

The 'Cruel Intentions' star also revealed that because of a rare condition called idiopathic hyperprolactinaemia, her nipples had produced a discharge resembling milk since she was seven years old.

Selma said: "I've always been someone that could make milk, ever since I was seven years old. Never had breasts, always had milk!"
