Age: 38
Occupation: Actress/Comedian
First off all, Wiig saved Saturday Night Live from sucking into oblivion with her closet full of characters. Secondly, Wiig put female comedies on the map with her poop and sex filled comedy Bridesmaids. We have her to thank for the inspiration behind the slew of women-driven ensemble comedies (including Bachelorette and Save the Date) coming out this year.

DECADE ACHIEVEMENT: Earning an Oscar nomination for "Best Original Screenplay" with Bridesmaids.
