Oscar-winning actress and mother of two Gwyneth Paltrow sat down with Oprah and chatted about her fitness routine, dieting and her struggle with postpartum depression.

On how she keeps her fabulous figure:

"I just cannot diet. I think maybe it's the idea that you can't have something...I just can't do it. It's worth it to me to do that extra exercise so I can eat what I want and not think about it."

On postpartum depression:

"It was very strange, because I wasn't expecting it at all...After I had Apple, I would characterize it as post natal euphoria. I was on cloud nine, I was in a bubble and then when I had him I didn't feel ok, I didn't feel right...[Moses] came out and I thought 'it's really strange, it's not the same, what's wrong with me?' I went down a slippery slope with it...It was about six months until I felt completely normal again. I didn't realize what was wrong with me."

On how BFF Madonna helped her through the tough times:

"She's given me a lot of great advice, she really helped me out of my post natal depression. She is one of the most caring women and also a very tough woman...She's very wise and has a very soft, soft side."
