Gwyneth Paltrow has credited he best friend Madonna for helping her through the worst of her post-natal depression – and likens her transformation to “molecular reorganisation”.

The Hollywood actress, who plunged under a black cloud mourning the 2002 death of her father, producer Bruce Paltrow, and then suffered another bout of depression after the birth of son Moses in 2006, puts her speedy recovery down to the Material Girl’s words of New Age wisdom.

“She really helped me out of my postnatal depression,” Gwyneth, 35, reveals.

“I had a very interesting talk with her one night. She was very wise about life’s bigger picture and when obstacles come up in our life it is for a very specific reason – they are there to teach us something that we haven’t learned yet.

“She made me see that my postnatal depression was an opportunity for me to change certain things about the way I was living. She really sort of reorganised my molecules in that situation.”

Oscar-winning Gwynnie, who has two children – Moses, two, and Apple, four – with Coldplay singer Chris Martin, admits she was shocked to suffer so badly after the relative ease of her first.

“After I had Apple, I would characterise it as postnatal euphoria,” she said in an interview with chat-show host Oprah Winfrey. “I was on cloud nine. I was in a bubble and then when I had [Moses] I did not feel OK.”

And giving a unique insight into the Madonna and Guy Ritchie family home, she gushed of the singer’s daughter Lourdes, 11, and sons Rocco, eight and David Banda, three, whom the couple adop­ted from Malawi: “Her children are phenomenal.

"The little guy [David] just kills me. He does dance routines from Madonna concerts on the living room floor.

“In fact my son and him battle it out to listen to either daddy’s songs or mummy’s.”
