Wood admitted she was worried about baring all for her role in Mildred Pierce but was reassured by her co-star, Winslet who has stripped on screen several times.
The 22-year-old actress also revealed she was recently shocked to discover she has fans.
"I've started to get fans now. It's weird, I was on set and there were all these girls lined up on the sidewalk and I assumed they were all there for Kate and they all shouted at the same time, 'Evan Rachel Wood, we love you' and I didn't know what to say so I just said, 'I love you too!'. I was so shy, that had never happened to me before."
