The Snow White and the Huntsman star recently revealed in the June issue of Australia's Madison:

    "My mother found [a letter I wrote]. It said, 'Would you please take me to orphanage, so that I can go and adopt a baby? I always knew I would adopt. Always."

The South African beauty has remained solo since ending her nine-year relationship with Stuart Townsend in 2010, and after the split, she wasn't sure she could raise a child on her own.

"You know, I don't think any mother aims to be a single mom," Theron confessed. "I didn't wish for that, but it happened."

But the blonde stunner admits the idea of marriage "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."

Theron also confessed in the June issue of InStyle mag, “Motherhood was something I always knew I wanted to experience. Adoption has been a great opportunity for someone like me who wants to have a family. ... I can only hope to be 10 percent of the mom mine was to me."

Charlize now wears a personalized "J" necklace, so her son is always close to her heart!
