A rep for Sandra previously declined to comment on reports of the adoption, and could not be reached on Thursday.
Sandra gushed about Louis in June, telling ET at the Minions premiere in London that her son is constantly surprising her. "Louis has no idea that I'm in this film," Bullock smiled. "He won't put two and two together -- at least not anytime soon. If he does, I'll be shocked. The kid surprises me all the time."

The actress also stressed just how much she loves her little boy. "I mean, like people go, 'Your adopted son.' I go, 'Please don't say that. He is my son!' I would give my life for him," she told ET's Kevin Frazier in June.
When she was crowned People magazine's "Most Beautiful Woman" in April, the Oscar-winning actress also gushed that it's her role as mom that actually makes her feel the most beautiful. "I was putting [Louis] to bed and told him that even when I'm old and gray and more wrinkly than I am now, I'll still love him and want to tuck him in," she recalled to the magazine. "And he asked why I have wrinkles, and I said, 'Well, I hope some of them are from laughing so much.' And he touched my face and said, 'You're not old, you're just happy.'"
