The `Iron Man 2` actress - who has two children, Apple, five, and Moses, four, with her husband, Coldplay singer Chris Martin - is keen to expand her family but isn-t sure when.
She said: "I would love to have another child at some point. But I feel very, very lucky that I have two healthy, nice ones."
Although she loves her kids, Gywneth admits on occasions she has to wear earplugs because they are so noisy.
She added during an appearance on `The Ellen DeGeneres Show`: "They`re great. They`re so sweet. But noise is just part of it. They`re kids and they have to do what they have to do. You just have to wear earplugs sometimes."
The 37-year-old star always reaches for the earplugs when her kids get out their noisy toys.
She explained: "With all these toys that makes noise, instead of smashing the toys when I haven`t slept and am losing my mind I just put on headphones or earplugs."
