Even though they live a lavish life, Gwyneth Paltrow admits that her marriage to Coldplay's front man Chris Martin is not always a smooth sail.

In her intimate interview with InStyle magazine, the actress revealed that she can sometimes clash with her husband artistic temperament. Gwyneth and Chris celebrated their nine year anniversary last Wednesday, but disappointingly, they were not together to cherish the moment.

"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 40-year-old actress answered when asked about the most difficult part of being married to Chris.

But despite their differences, Gwyneth said that she would not change a thing about her marriage. She said that both of them have the strength to be independent from each other and that's also why their marriage is strong.

The actress is currently in Dubai for work appointments with Hugo Boss. But although she was away from Chris during their 9th year, a source said that the couple had an early celebration before Gwyneth flew for work.

Gwyneth also admits that she welcomes the possibility of another baby. She already has an 8-year-old daughter and a 6-year-old son with Chris. But the actress hinted that she may not be done and would still consider another addition to the family.

"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!"

"When Apple was born, she had the hugest blue eyes. I looked into them and she was looking at me, and I felt like, 'You are here to teach me everything,'" the actress shared during her interview. "After Moses was born, I had postpartum depression. It was a difficult time and because of that, I believe I have an extra empathy for him and he for me."
