Eva Mendes says the secret to her flawless skin is her meat-free diet. She only eats fish to keep her skin healthy.
She also drinks three litres of water a day to stay hydrated.
"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," contactmusic.com quoted her as saying.
But she has other beauty mantras too.
"I believe beauty starts from within, so I exercise, eat well and drink three litres of water a day. It all begins with hydration," she added.
The 38-year-old even limits the amount of time she spends in the shower to conserve water.
"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," she said.
