Charlize Theron almost dropped out of Snow White and the Huntsman when she knew she was going to become a mother.

The 36-year-old actress adopted her son Jackson, now six months, in March and is pleased she decided against pulling out of the film because she now thinks becoming a parent to the little boy has made her a more creative person.

"When I first heard my son was coming into my life, I didn't want to make the film. But having him has changed me and made me a lot more creative as a person. I love being a mum so much. There's nothing better than rolling around with the baby in my PJs," she said.

Charlize recently admitted she never expected to be a single parent but always wanted to adopt: "You know, I don't think any mother aims to be a single mom. I didn't wish for that, but it happened. I always knew I would adopt. Always."
