Brooklyn sure has his dad's strong facial features. Although there is a lil' Victoria there too, this boy would definitely look like David when he grows up. And I bet every girl cannot wait long for this.
From the expression and the way she dresses up, Alice is without doubt, and definitely the daughter of Tina Fey. I hope that she has her mom's humor too because it would be awesome that they'll both star in their very own mother-daughter comedy sitcom. Better cross your fingers for this and make a wish on a falling star that this will happen!
