Jessica Alba is proving that she’s a beauty with a brain.

“For a long time, I didn’t think I was smart. I felt like an imposter,” Alba shared with Self magazine. “It’s not until you feel whole in yourself that you fit in anywhere. And it took me becoming a mom to actually feel that way.”

As the co-founder of the billion-dollar Honest Company, Alba, 34, credits her business-savvy mindset for her success.

“I’ve always been business-minded,” she said. “I approached Hollywood like a business … I was very calculated. I wanted to be treated like a guy; I wanted to put asses in seats. I saved my money, invested wisely, and marketed myself. I’ve been building my own personal brand over time.”

While pregnant with daughter Honor, 7, in 2008, the actress admitted that she was fearful of certain products her baby-to-be would be exposed to. With the desire to welcome her first-born into a safe environment, Alba toyed with the idea of launching a company centered on the well-being of families.

“I was horrified by the realities around the use of chemicals, and also the link that these chemicals have to a lot of illnesses, from obesity to lung disease to cancer, allergies, eczema — all of it …,” Alba explained. “I was bringing this little person into this world and I thought, I want her to be healthy.”
