Drew Barrymore wants to have more children.

The actress is expecting her second child with husband Will Kopelman but already planning to expand her brood even more.

She told Women's Health magazine: "I'd love to have more kids. I think it's about being mentally healthier and then you are physically fit."

The blonde star, who also has 13-month-old daughter Olive, doesn't obsess about her looks during pregnancy and takes it in her stride.

She admitted: "I'm actually not really working out right now. It's a lot of fork up the food, shove to mouth, chew, repeat.

"It's about feeling good in clothes and knowing you can get dressed up in the evening ... but there's just no such thing as perfection. So if you're trying to get there, you're just torturing yourself.

"You're not supposed to look perfect while you're making babies. Making babies is the perfection."

The 38-year-old has also taken inspiration for her new Flower cosmetics line from her daughter.

She said: "I love doing the beauty line because it's so inherently feminine and so much of a celebration of women. I think about my daughter and how special that is to be making something that's so creative and empowering.

As she focuses more on her family life, the protective mother is determined to give her kids a childhood that includes plenty of playtime.

The former child star added: "I didn't grow up around a lot of family. I grew up so fast and exposed to everything, and I think being a kid for as long as possible is just awesome -- I would love that for my kid."
