Machete Kills actress Jessica Alba has penned a lifestyle book offering parenting advice to promote “honest living” among her fans.

The 31-year-old star, who has two daughters, Honor (4) and Haven, 17 months, with her husband Cash Warren, explained that she decided to write the book after becoming frustrated with the lack of trustworthy parenting information available to first-time mums.

A statement on Alba's lifestyle website The Honest Company reads: "The Honest Life recounts Alba’s personal journey of discovery and reveals her tips for making healthy living fun, real, and stylish, while offering a candid look inside her home and daily life... Her solutions are easy, chic, and daily life... Her solutions are easy, chic, and down-to-earth: they’re honest."

The Honest Life: Living Naturally and True to You hits shelves on March 12.
