This alluring, auburn-haired model-turned-actress received a great deal of attention for her portrayal of the nymph-like muse Sheela in the erotic comedy "Sirens" (1994). Australian native Macpherson began modeling at age 18 when spotted vacationing in Aspen, Colorado. Her strapping (she stands six feet), voluptuous look soon caught on and Macpherson adorned the covers of such magazines as ELLE and SPORTS ILLUSTRATED.
