Tina Fey turns 42 today! Born Elizabeth Stamatina Fey, the writer and actress has gone from shaggy-haired Saturday Night Live scribe to the star of her own Emmy-winning show 30 Rock. "I had a pretty rough puberty," the Upper Darby, Pennsylvania native has said. "Growing up as a girl is always traumatizing, especially when you have the deadly combination of greasy skin and getting your boobs at 10." Today, the mother-of-two and Bossypants author is head-turning beautiful, or as pal Rachel Dratch called her, "a total hottie." See the funny lady's amazing beauty evolution in the gallery.
