'I will never get my pre-baby body back': Candid Jessica Alba on the downside of motherhoo d

As she awaits her second child, Jessica Alba can't help but marvel at the miracle of pregnancy.

'I saw how incredible and amazing it is to be a woman and to be able to create a life,' the 29-year-old says of welcoming her first child Honor, now three.

'There’s a reason why certain areas of the body are desirable - because it all leads to reproduction,' she says.

'There’s a science behind it all. It’s not just to sell whatever you’re selling on a billboard or a magazine or a movie.'

Pre-baby body: Jessica in 2005's Into The Blue

But in a candid interview with the latest issue of Allure magazine, she admits that motherhood has changed her body forever.

While the star, who became famous for her bikini body in 2005's Into The Blue, worked hard to get back into shape following the birth of her first child, she as accepted that she will never fully regain her pre-pregnancy figure.

 

'I can’t ever get down to the weight I was before I had Honor,' she says.

'My body’s just different. The jeans just sort of zip up differently, and things hang differently. It’s a miracle what happens, but you definitely are different afterward.'

'Unless you’re Gisele,' she adds with a chuckle.

The star, who is married to production assistant Cash Warren, is also doing her best to embrace the ageing process.

Of her impending 30th birthday, she says: 'You get to be more complicated and complex and dynamic, I believe, the older you are.

'When you read scripts, there’s usually women in their 30s who have great roles, or women in their late teens and early 20s. And in that in-between time, it’s tough to find your footing. Later, there’s just more happening in someone’s life.'

And the Fantastic Four and Little Fockers actress is certain the best is yet to come,

'According to some people, I peaked in my early 20s,' she adds with a chuckle. 'I was like, "Oh, really? I feel like I’m getting better".'
