Gwyneth Paltrow Calls Marriage 'Challenging,' But May Want More Kids

On the most difficult thing about her marriage, Paltrow revealed, “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.”

Gwyneth, who turned 40 in September, is already mother to Apple, 8, and Moses, 6, hinted that she may not be done with childbirth. “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!”
