The Oscar-winning actress - who gave a home to baby Jackson, who is from her native South Africa, in March - had always thought about adopting but never contemplated doing it without a man in her life.
The Prometheus actress told Australian magazine Madison: ''You know, I don't think any mother aims to be a single mom. I didn't wish for that, but it happened.''
She added: ''I always knew I would adopt. Always.''
The 36-year-old actress has always been open about her desire to adopt, saying in 2011: ''I'm open to everything in life. I want a baby. If it would happen tomorrow I would be very happy.''
Charlize - who stars alongside Kristen Stewart in her new film, Snow White and the Huntsman - spilt from her partner boyfriend of 9 years, Stuart Townsend, in 2010.
But the 36-year-old screen beauty won't be getting hitched any time soon as she thinks marriage is nothing more than a ceremony.
She said: ''It has never been that important to me. I don't know why exactly. Some might say it's because my parents didn't have a good marriage, but I don't think so. I treat my relationships like marriages.
The ceremony isn't that important to me.''
