"I know she's already a great mom and she's doing wonderful," he added.
Leigh Anne Tuohy -- the woman on which The Blind Side is based -- met Louis earlier this month.
"[Bullock] said, 'Here he is, what do you think? You better like him,' and I could eat him with a spoon," Tuohy told Access Hollywood and The Billy Bush Show. "He's the most beautiful little baby... He's got eyes that have wisdom. I could just stare at him all day."
