Gwyneth Paltrow wants to have another baby. The 'Iron Man' actress is keen to add to her brood - she already has four-year-old Apple and two-year-old Moses with husband Chris Martin - because she is worried she may regret not having more children in the future.

She said: "I may force myself to do it one more time because the result is so worth it. And also my late dad Bruce said to me that his only regret in life was that he had only two children and he didn't have more." Gwyneth also admitted she is thinking of adopting a child like her friend Madonna, who adopted two-year-old David Banda from Malawi, as a way of giving something back to the world.

She said: "I do feel we're so fortunate, and we kind of owe it to humanity. We have a lot of love to give and a lot of resources." The 35-year-old star is full of praise for Madonna, insisting she is an inspiration to her. She added to Harper's Bazaar magazine: "She is so physically beautiful and fit, it's just crazy. I think part of the reason she looks so good is that she's always striving for more knowledge. She is a very interesting woman."
