Jessica Alba has stormed with success from acting, to business, to lifestyle. One thing that might shock you is the reason she won't strip for roles! Keep reading to learn more from her recent Glamour interview.

The June cover model, who was brought up in California and raised Catholic, explains she does not want her family seeing too much.

"I don't want my grandparents to see my boobs. That's it. It would be weird at Christmas," the star confessed.

"And, I mean, really, if you look at the movies I have done, getting naked would never "elevate" the picture."

Before marrying Cash Warren, who she met in 2004 filming "Fantastic Four," the actress was engaged to "NCIS" star Michael Weatherly.

"Relationships can be tough. With Michael, I didn't have a voice yet, and he was so much older," Alba explains.

The "Honey" star has two daughters with Warren, who she has been married to for six years, but relationships were not always easy.

"Where I was from, you had to answer to a man if he was the breadwinner," Alba said.

"My mom told me that didn't need to be the case for me - I didn't need to rely on a man. She taught me how to hustle. I was determined to be financially independent. So I started making my own money when I was 12 (with acting). That was freedom."

The Daily News notes Alba founded The Honest Company, which focuses on eco-friendly, natural health products.

"I think right now is a great time for female entrepreneurs," she claims.

"I've learned that until you can prove that your business works, it's only an idea. You have to know your stuff," the star continued.
