Sexy star Rebecca Romijn has lost a staggering 60 pounds since giving birth to twins four months ago - and it's all thanks to breastfeeding.

The model-turned-actress reveals she was 35 pounds 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 haven't been able to work out that much because I have twins. It's impossible to get back into a regular schedule. Breastfeeding is the very best diet I've been on. It's amazing. It's like you have to eat 5,000 extra calories a day or you can't produce enough food for them. So, that's been fun as well."

But Romijn insists she still has more weight to lose: "I'm not pretending to be back to the shape I was in beforehand. I still have a way to go."
