Actress Keira Knightley seems to have problems avoiding props on set and breaks important items while filming.

According to contactmusic.com, Knightley was upset when she broke a Chanel necklace and a lighter when she was shooting the movie 'Atonement'.

She said: 'I was wearing a Chanel necklace and it got stuck. No one could budge it. We had to phone Chanel to ask if we could just break it. By this time the filming had come to a complete standstill. I also had to light a cigarette and lighters always break for me on film sets. At this particular moment the lighter had broken for about the millionth time.'
