The 30-year-old actress - who already has three-year-old daughter Honor with husband Cash Warren - has already begun getting a nursery prepared, but is particularly excited about expanding her family because it takes parenting "to another level".

She said: "It feels like you`re really officially, really truly a mother when you have two kids. One kid you?re a mother for sure but two takes it to another level."

Discussing her baby room plans, she added: "I use stains and paints that are eco-friendly and safe."

The `Spy Kids` star is particularly happy with husband Cash because he has been helping her out.

She added to People.com: "He`s been very agreeable since I`ve been pregnant!"

Jessica has previously revealed she is already planning how to get her body back into shape following her pregnancy.

She said: "Working out every day for even just 45 minutes is good for my mental state.

"Getting dressed and actually doing it is the worst. It`s hard to get motivated.

"In the gym, I have, like, five things to distract me: TV, iPod, magazines.

"Working partners are good, too, so you can chat and not just drown in your own misery. Sorry, does that sound bad? I just hate working out."
