Cameron Diaz appears to have been on edge and had gone into hiding shortly after a man was shot out of doors at the nightclub House of Blues in Los Angeles. While this was going on Cameron was working her way through the cocktail menu. The adult male who was shot lived but left Cameron a nervous wreck. After listening to the rapid fire of shots and watching the sequence of squad cars and ambulances which occupied the streets outside the ritzy establishment, Cameron, 36, made up her mind that she would prefer to eat her own food than embark out into the meanspirited streets of Los Angeles once more. Therefore she's confined herself up in her residence until her hands stop trembling.
