Sexy star Rebecca Romijn has lost a staggering 60 pounds (27.2 kilograms) since giving birth to twins four months ago - and it's all thanks to breastfeeding.
The model-turned-actress reveals she was 35 pounds (15.8 kilograms) lighter three weeks after Charlie and Dolly were born - and she has lost the weight without a work-out plan.
She tells news show Extra, "I havent been able to work out that much because I have twins. Its impossible to get back into a regular schedule.
"Breastfeeding is the very best diet Ive been on. Its amazing. Its like you have to eat 5,000 extra calories a day or you cant produce enough food for them. So, thats been fun as well."
But Romijn insists she still has more weight to lose: "Im not pretending to be back to the shape I was in beforehand. I still have a way to go."
