Keira Knightley believes her hot temper is inherited from her actor father Will Knightley, and she loves to release her anger by smashing glass. The Pirates Of The Caribbean beauty, 22, enjoys getting rid of her angst by throwing glasses, and calls the act "therapeutic". She says, "I have the Knightley streak. He gets angry at inanimate objects. I find it therapeutic to throw glasses even if you have to spend the rest of the night on your hands and knees collecting pieces of glass."
