Angelina Jolie did not want to have biological children until partner Brad Pitt changed her mind.

Speaking to W magazine, the actress commented that the turnaround is "[just] one of the life-changing things" he has done since the pair got together.

"I was absolutely never going to get pregnant. I never felt that it was the right thing to do," she said.

However, the Tomb Raider actress reconsidered her stance on the subject while watching Pitt develop a bond with adopted children Maddox and Zahara.

Jolie continued: "I suppose in my heart I realised he was happy with them as his children, completely. I knew he would never see them as different, and that gave me a certain peace."

"I suppose I just looked at him and loved him and just felt open to [getting pregnant]. I suddenly wanted to. It's one of those things you can't explain," she added.

Pictures of Jolie breastfeeding newly-born twins Vivienne and Knox will reportedly be published in November's issue of W.
