Evangeline Lilly refuses to take her success on hit US TV show Lost for granted, because she fears becoming a broke actress again.

Before the former model hit the big time with Lost, she used to struggle to find enough money to buy food.

And it's that memory which keeps the 26-year-old Canadian firmly grounded.

She says, "Lost has been great for me, but I remind myself that any day now I could go back to the days when I was waitressing and barely able to afford to eat or go anywhere because I had a broken-down car."
