Jessica Alba Double Corset: Actor Shares 'Brutal' Pregnancy Weight Loss Secret; Was it Worth It?

Jessica Alba has revealed the secret to her post-baby weight loss and it's a sweaty one: Wearing a girdle.

The mother of Honor and Haven disclosed in an interview with Net-a-Porter's magazine that she wore a double corset every single day and night for three months straight.

"I wore a double corset day and night for three months. It was sweaty, but worth it." said the 31-year-old actress. "It was brutal; it's not for everyone."

Her weight loss tactics may be making headlines now, but Alba was forthcoming about this process in 2011 in a Lucky Magazine interview.

"I wear a girdle around my tummy from the moment I give birth until it doesn't feel loosely goosey anymore-that takes a good two to three months," she told the fashion magazine. "It's spandex with Velcro."

While the Jessica Alba double corset weight loss method was brutal, motherhood was anything but for Alba.

"My approach to acting now is different -- I'm fearless because I have nothing to lose," Alba said, according to New York Daily News. "Before [children] my identity was wrapped up in every decision. Now, I don't care. It could be a pile of s*** and you could think it was the worst thing you ever saw, but I still had the best experience."

Her other pregnancy secret, as told to Lucky Magazine, is prenatal yoga.

"I have a bad back and bad knees and it really prepares your body," said Alba. "The more limber you are and the stronger you are, the easier your birth. And isn't that what everybody wants?"
