Tina Fey

Tina Fey can make a joke out of virtually anything -- so why should the aging process be any different? The 42-year-old funny woman penned a New Yorker article in February 2011, in which she pokes fun at the way Hollywood views middle-aged women. "Science shows that fertility and movie offers drop off steeply for women after forty," Fey writes. In that article, she also noted that women, at least in comedy, are labeled 'crazy' after a certain age -- well, there's nothing crazy about Fey's success. Her sitcom 30 Rock has collected numerous Emmys since its start in 2006, and her 2011 memoir Bossypants sold more than 1 million copies. And did we mention she's a mom? Fey raises daughters Alice, 7, and Penelope, 1, with husband Jeff Richmond.
