She went to UCLA to study biology, but dropped out to become a model in Japan. She moved back into acting with a Mexican commercial for AmEx and then followed that up by being Isabelli Rosselini's nude body double in "Death Becomes Her", where she also met her future husband, Adam Beason, who was the director's assistant. The couple currently live near L.A. with two Italian greyhounds, Zoe & Leo.
