Jessica Alba didn't always "make the right choices"

The 'Sin City' actress has admitted she often struggled when deciding which roles to accept, but launching her own eco-friendly lifestyle company has given her a new self confidence in her abilities.

In an interview with the April 2013 issue of Latina magazine, she said: "Honest Company has weirdly allowed me to be more creative in my roles, and really work with people I love and appreciate and want to learn from. This is where my work is now.

"For me, acting was a lot about making the right choices and trusting my instincts. I didn't always listen to my gut and make the right choice."

The 31-year-old beauty - who has daughters Honor, four, and 20-month-old Haven with husband Cash Warren - launched the Honest Company, which specialises in organically-produced nappies, baby wipes and bath products, after becoming a mother as she feared big brand baby products could be harmful to her children.

She said: "It's really hard to find baby products that use non-toxic chemicals that mums can trust. Major corporate brands that label their products 'eco-friendly' or 'non-toxic' are usually referring to the way they make their packaging, not their product."

The actress has also written her own book, 'The Honest Life', dispensing tips on living well, parenting and healthy eating.

She recently said: "I absolutely do these things. That's why I wrote the book. There's lots of options, like delivery services for fresh produce that is organic, if people just want to do a couple of things in the book that are super-easy ... You can take what you want from the book."
