The brunette beauty – who is married to Brian Austin Green – has a strict healthy eating regime, and makes sure she sits down for a meal five times a day alongside vitamin and mineral supplements.
She said: “I eat five times a day and don’t diet, but I do eat healthily – mostly raw and vegan food with no dairy.
“It’s not always possible with travel and filming, but I try.
“I also take supplements like silica and fish oil religiously.”
Megan believes femininity is an “attitude” and thinks beauty comes from “simplicity and elegance”.
She told Marie Claire magazine: “My definition of beauty is simplicity, elegance and sensuality.
“I think that when a woman is in harmony with herself and remains true to her values, she will glow naturally. Femininity doesn’t depend on what you wear or how you look. It’s an attitude.”
