Gwyneth Paltrow wants more children.

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."
