Career: Fashion Designer
Famous Family: Musician-activist Paul McCartney (father); photographer-activist Linda McCartney (mother)

She may not have inherited her dad's musical talent, but Stella McCartney sure has carried on her parents' love of animals. The lifelong vegetarian is a bit of an anomaly in the fashion world, refusing to use any leather or fur in her designs. McCartney has been known to wear her animal activism on her sleeve, literally; a line of athletic wear she created for Adidas stated "suitable for sporty vegetarians" on the arm.
