Jada Pinkett Smith

Unfortunately, Jada Pinkett Smith also aged herself considerably when she decided to dress like a 17-year-old for the 2012 Nickelodeon Kids' Choice Awards, which she attended with her children Willow, 11, and Jaden, 13. Jada's ensemble -- consisting of a pink Catherine Malandrino jumpsuit, cropped denim jacket, and patterned platform sandals -- would have looked cuter on Willow, but doesn't work quite as well on a 40-year-old. As for her shaved side ponytail ... can you say ridiculous? (3/31/2012)
