"She’s so smart and she's already talking a lot," the Mad Money star told David Letterman last night. "She's already a wonderful artist!"

Katie seemed exultant of her matronly status, claiming on occasion to approach her sleeping daughter and "kind of kiss her and see if maybe she’ll wake up.""

She even credited her family for her recent finish in the New York Marathon, claiming "Tom and Suri met me at mile 18, and I really wanted to get in the car at that moment. Luckily, they pushed me through!"
