Jessica Alba isn't upset about never appearing on the cover of American Vogue.

The 34-year-old actress, whose eco-friendly brand, The Honest Company, was recently valued at one billion dollars, recently posed for the front of Forbes' issue on the richest self-made women in the US and thinks it's just as prestigious an honour as being featured on the monthly fashion bible.

The brunette beauty said: ''I've never been on the cover of Vogue, but I've been on the cover of Forbes.''

The 'Sin City' star is a huge fan of fashion and doesn't enforce a strict dress code among her employees.

She told the September issue of Allure magazine: ''It's business casual. We do have a tech company - we're not very stiff people.''

But the brunette beauty wasn't always so stylish and embraced ''nineties grunge'' in her teens.

She added: ''I got my bellybutton pierced the second I could. I wanted to shave my head and pierce my nose, and my mom said she was going to make me stop acting, I was like, 'Oh, that's so mean.' ''

Jessica is preparing to launch a new ''clean'' cosmetics line, Honest Beauty, but husband Cash Warren and daughters Honor, seven, and Haven, four, aren't fans of all of her treatments.

She said: ''It shocks him whenever I wear [face] masks. Especially when I wear those big paper masks that make you look like a serial killer. My kids don't like that, either.''
