Eva also drinks three litres of water every day to stay hydrated. She revealed: "I eat a lot of fish – I haven’t eaten any meat at all for several years now – and I’ve noticed that my skin looks a lot better and much healthier.
"I believe beauty starts from within, so I exercise, eat well and drink three litres of water a day. It all begins with hydration."
Just as the 38-year-old screen beauty – who is the new face of Pantene Drink Up – is careful about what she puts into her own body she is also conscious about being environmentally friendly.
Eva – who is dating ‘Drive‘ actor Ryan Gosling – even limits the amount of time she spends in the shower to conserve water.
She is quoted by website SkyLiving as saying: "Taking a five minute shower always helps the environment. Plus it’s a great way to make sure I’m out of the house sooner therefore always running on time."
