The actress, who has four-month-old twin boys, Cy and Bowie, with husband Marco Perego, admits it will be "painful" when her maternity leave comes to an end soon, but says she has bills to pay.

The 36-year-old star, who is gearing up to shoot the 'Avatar' sequel, said: "It's painful. I'm pretty sure that every parent -- not just every mom -- would [take time off] as long as your work doesn't suffer. But we have to pay bills and at the end of the day, I think that's the best example we can set to our children. We're very determined and we can't just leave everything behind and just focus on them. But it's painful."

But Zoe is glad she and artist Marco, 35, have lots of people to rely on for support and says their nanny forces them to go out on dates.

She told UsMagazine.com: "We have a village, but it's fun. Like, it takes three people [to care] for two? What the hell?! This is us tonight with a nanny kind of telling us, 'Get out. You guys need to go breathe.' "

While she has help at home, the brunette beauty is eager to regain her pre-pregnancy figure alone.

She explained: "Whenever they are taking naps, my husband and I are doing little push-ups here and there and everything. I want to prove to myself and help people understand that sometimes you don't really need a trainer. You can do it on your own."
