Gwyneth Paltrow On More Kids: "Part Of Me Would Love To Have Another ... Of Course, I’m Old Now!"

Gwyneth Paltrow covers the new issue of InStyle U.K. and while the mag borrows some quotes from her interview with the U.S. edition earlier this year, there's a few new tidbits, specifically about her desire to have more children!

The 40-year-old actress says she thinks about giving son Moses and daughter Apple a younger sibling, telling the mag, "My brain says, 'Oh, I think I’m done, the kids are big now and I don’t want to go back to changing diapers.' But a part of me would love to have another. Of course, I’m old now!"

Gwyneth, who was interviewed by pal Diane von Furstenberg for the mag, added, "I look for an interesting supporting part about once a year. That’s the most I can manage. Some women can do it and that’s fantastic, but I can’t. You make choices as a wife and mother, don’t you? You can’t have it all. I don’t care what it looks like."

So what does Mrs. Goop say is the hardest thing about her marriage to Coldplay frontman Chris Martin? "Probably our artistic temperaments together. Artists are sensitive; there are ups and downs, mood-wise. Musicians need a certain gravitas and focus in order to write. The temperament that goes with someone who is creative can be challenging."
