The 45-year-old Oscar-winner began the adoption process with husband Jesse James four years ago. But the couple kept the news private until now.
"He's just perfect, I can't even describe him any other way," the actress revealed the happy news on People magazine, "It's like he's always been a part of our lives."
However, Bullock also announced that she had filed for divorce for the sake of Jesse James’ cheating scandal.
She is now adopting the baby son as a single parent.
