Malin Akerman is an eco-friendly mother.

The 'Rock of Ages' star admits she takes inspiration from Jessica Alba and enjoys using items from her business The Honest Company - which specialises in organic nappies, baby wipes and bath products - when she changes the bottom of her six-month-old son Sebastian.

Speaking to E! News, she said: ''We use a lot of Jessica Alba's products from The Honest Company.

''We switch off between cloth diapers and Seventh Generation diapers. His clothes are organic cotton...He's going to think he's an alien he's going to be so green!''

The 35-year-old actress believes she's lost her baby weight by going on regular hikes with her rocker husband Roberto Zincone - who she married in 2007 - and by attending spin and Pilates classes at her local gym every week.

She explained: ''It's very easy to be green while working out, you can go on hikes here in California. We live right by Griffith Park and now I've got the stroller--a little added weight. I wish I could tell you there's a magic pill, but there isn't. You go back to the gym.''
