Charlize Theron has already established herself as a highly accomplished actress, but she's about to embark on her most challenging role yet: motherhood. Theron's rep confirmed the exciting news in a statement to Us magazine on March 14, saying, ""Charlize Theron has adopted a child. She is the proud mom of a healthy baby boy named Jackson.""

While very few details about the adoption have been released, a source close Theron revealed that little Jackson was born in the United States and is of African-American decent.

And even though the 36-year-old star will be taking on the full responsibility of parenting all by herself, the insider claimed the first-time mom has never been happier. ""She has always wanted to be a mom,"" said the source. ""She is glad to be able to do it on her own now and is so happy to be a mom.""

Theron split from actor Stuart Townsend in January 2010, ending a nine-year relationship. This prompted her to begin a whole new chapter in her life, which now includes a baby. If she's as great of a mother as she is an actress, it's safe to say the child is in very good hands.

Congratulations to Theron and her little bundle of joy!
