Naomi Watts completely transformed into Jackie Kennedy while filming Ryan Murphy's upcoming series, American Love Story. The first shots of Watts, 56, in character as Jackie - who was married to President John F. Kennedy and died from cancer at age 64 in 1994 - were released on Monday, July 21, and made Us do a double-take. Instead of donning her go-to platinum blonde strands, Watts rocked chocolate brown hair cut to her shoulders and styled in a bouncy blowout, just as Jackie wore.
