Christina Aguilera says brestfeeding helped her shed baby weight

Christina Aguilera has revealed the secret to her weight-loss since giving birth two months ago - breastfeeding.

"I think they say that when you're breastfeeding, you know, your weight kind of slims down. It's a little easier," the 'Dirrty' star told Access Hollywood.

"It's like a workout within itself. It’s very tiring actually and you find yourself snacking more often."

The singer isn't the only celebrity to credit breastfeeding with helping them lose their post-baby pounds.

Actress Naomi Watts recently revealed that breastfeeding also helped her regain her svelte figure.

She said: "Three weeks before we started filming my new movie 'The International' I decided that I better get into changing my body back again.

"They gave me a trainer and it was very effective and also breastfeeding. That's how you drop weight. Even though you're just eating all the time he is eating too."
