Tina Fey on Her Youngest Daughter, Penelope: "She Will Just Take You Apart"

Tina Fey stopped by The Ellen DeGeneres Show on Tuesday and opened up about her two favorite gals: her daughters, Alice, 10, and Penelope, 4. With Christmas just a week away, Tina admitted that she worries Penelope might be on the naughty list this year, saying, "If that happens, then there will sort of be hell to pay for Mommy. My older one is sweet and really easygoing, and my little one is rough. When she is mad at you, she will just take you apart." She also talked about what it was like filming her new movie Sisters with her best friend, Amy Poehler. See the full video above, and then check out the dynamic duo's best moments together.
