Is the model laughing uproariously......or screaming in agony?
Fingers pressed to her temples because her head is exploding with a sudden migraine? (Meanwhile shrieking to the heavens for relief from the unbearable pain?)
Or her head thrown back at an unlikely angle because she just thought of something unbelievably hilarious and had a spontaneous eruption of mirth?
Either way, I think we can all agree that it's rather an odd pose.
