New mom Naomi Watts visited “The Late Show with David Letterman” last night. This woman really is genuinely lovely! I love how she freaks out Letterman when she mentions “milking!”

Naomi shares stories about her two baby boys with fellow actor Liev Schreiber, losing 75% of her brain power do to a “lactose lobotomy,” having a hands-on-daddy, meeting Liev for the first time at the MET’s Costume Ball & cornering him for his digits, and her 40th birthday party.

Check out Naomi in her latest film with Clive Owen entitled, “The International.” It hits theaters this Friday.
