The world of celebrities these days still holds some mystery, even if most of your favorite Hollywood heroes lead their lives under a pretty strong spotlight. Though most celebrity moms are fairly private when it comes to their children and families, many celebrity moms have taken to speaking out on a number of subjects to do with motherhood. Including the way they're raising their children. But even though many celebrity moms have become more public about their choices in raising their children, there are still plenty of celebrities you didn't realize were crunchy moms.

If there was ever any doubt that she is a crunchy celebrity mom, Vanity Fair noted that Jessica Alba created an entire company dedicated to natural products for her babes. According to Vanity Fair, The Honest Company came to be when Alba was pregnant with her first child, and washed her unborn child's clothes in a detergent that caused her to break out in hives. So she went searching for a better product, and when she was unable to find it, she decided to create her own. The rest is billion dollar, natural mama history.

In an interview with The Telegraph, Natalie Portman made it clear that she's a pretty crunchy mom. Portman told the publication that motherhood has made her a lot less judgmental. “Everything is cool, there are no rules — I mean, apart from not hurting your kid,” Portman said. “Some people breastfeed until their babies are 5, and some don’t breastfeed at all." The actress went on to say that there's no 'right' way to be a good mom, and that she's learned that everyone has to do what's right for them. Sounds like the credo of an open-minded crunchy mom, doesn't it?

The finding, along with her own journey in becoming vegan, prompted her to write a cookbook, Mayim's Vegan Table. “To me, it’s more of a lifestyle decision,” Bialik said to One Green Planet. “You can pay now for organic food, or you can pay later for the healthcare costs.”

Richie's pure parenting methods were spotlighted on The Doctors, when the doctors shared that Richie keeps her house sugar free and BPA free.
