The news comes almost two months after Theron and actor Sean Penn ended their relationship. It was previously reported that Penn wanted to adopt Jackson with rumors of another sibling coming soon.

"Sean always knew that to truly earn a place in Charlize's heart, connecting with Jackson was one of the most important parts," a source said. "There is still talk of adopting again and giving Jackson a brother or a sister."

Of course, this news turned out to be half true- Jackson did get himself a little sister, but Theron is taking care of both of them as a single mom.

Theron, who turns 40 this week, made it clear that she is happy with her life right now. Posted via Times of India, the actress talked about why she is excited to be hitting her 40's.

"People are so concerned for me. It's okay," she said. "It's such a weird thing that we put so much...I think especially for women. I'm so happy to be in my 40's and not be in my 20's and worried about whether I fit into my skinny jeans or whether I will be able to get into that club."
