Kristen Stewart spotted At LAX Wearing Arm Splint

Kristen Stewart has landed back in Los Angeles, as of today. Here are photos of her at LAX, sporting what looks like a cast or a splint on her left arm. So, what happened to Kristen Stewart’s arm? Did she injure it during a feisty Breaking Dawn action scene? Does she have a bad case of carpal tunnel? Did she get it caught in the mixer when she was cooking? Who knows??
