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.
Meryl Streep (L) and Sandra Bullock had tied for Best Actress at the 15th annual Critics' Choice Movie Awards held at the Hollywood Palladium in Hollywood, California on Friday (January 15).
Sandra Bullock, star of The Blind Side, shared an intimate kiss with Meryl Streep, star of Julie & Julia, as they accepted the award onstage.
"This is an honor." Bullock exclaimed after the kiss.
Later in her acceptance speech, Bullock said she and her co-winner have a lot in common, saying that she loves "food and $ex like Meryl. ... That's how similar we are. You guys just didn't notice it until now."
"Meryl is a good kisser." Bullock ended her speech by admitting.
