Kristen Wiig is just one year shy of the BIG 4-0!! Today she is celebrating her 39th birthday and in honor of the BIG day, we here at Hollywire thought it would be nice to pay homage to her many, many comedic endeavors. She’s made us laugh with her hilarious SNL skits and made us laugh even harder when she took her talents to the big screen in movies like Knocked Up and last year's classic Bridesmaids (which she co-wrote and was Oscar-nominated for!).
