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.'"
