Jessica Alba is living proof that someone's outside does not always match what is going on inside her head.

In the March issue of Cosmopolitan magazine, the Latina beauty insisted she has long identified more with her masculine side than her well documented feminine traits.

"Most of my life, I identified more with my masculine side," she said. "I was kind of aggressive and super masculine in my early 20s -- even into my mid-20s. I got boobs when I was young ... and I was like, 'What do I do?'"

The 34-year-old mother of two went on to admit she was never the woman Hollywood marketed her to be.

"I was always feeling angry, like an impostor. I learned how to be cool with the feminine later in life," she said.

Alba's personality has helped make her a force in the boardroom. Her confidence partly explains the huge success she has seen with her business, The Honest Company.

"I'm in a man's world in business," she said. "But I know what women want -- [men] don't... Whenever [male colleagues] question me in meetings, I'm like, 'Go home and ask your wife. This is a pointless conversation. Go home and talk to her.'"

Alba also recently entered the world of fashion, announcing a partnership with denim brand DL1961, for which she will design up to 10 pieces for the Fall 2016 collection. Describing the upcoming venture, Alba said she plans to use her own personal experiences with jeans and fashion in ultimately deciding what pieces she brings to the table.

"I remember having to lay down to button up those tiny Daisy Duke shorts because I had a big booty," she said. "I had to squeeze into my friends' jeans because my mom wouldn't buy them for me. The jeans that I'm designing are going to celebrate women's bodies and show off those curves."

A collaboration with DL1961 seemed a natural fit with the environmental mindset of The Honest Company, given the brand's already high standards.

"DL1961 is a thoughtful company in the way they go about creating denim, and that angle was important to me as well," Alba added.
