Who Bruised Paris Hilton?

Paparazzi Queen Paris Hilton was doing her usual daily routine, coming out of her house and going shopping meanwhile surrounded by tons of paparazzi, when she decided she wanted to sneak away and do some shopping in the privacy at the ritzy Beverly Center shopping center. She knew she could come here and be protected by the overzealous security guards that guard the place of paparazzi. Upon arrival, Paris and her friend went up the elevator and disappeared for a while in the mall. When we finally caught up to her, Paris and her friend were grabbing a drink at the Coffee bean stand. She had taken her sweater off and was waiting to pay for her drinks. We began to snap (photograph) her, but as soon as she realized she was being photographed she quickly put her sweater back on. Not knowing yet that her arm was bruised, we kept snapping her like any old day. Paris, along with the paparazzi that were photographing her (including myself), created a great commotion inside the mall. Within 10 min, the store where she was shopping was surrounded by curious fans who wanted a peek at the heiress. Security was overwhelmed by the crowd so they took her out the back and took her to her next shopping destination, Pottery barn. There she was approached by two gentlemen who were visible overwhelmed by the sexy paparazzi queen.
Paris is not a stranger to being photographed with bruises on herself. A few years back she was photographed with bruises on her face and arms. There was speculation that her then boyfriend, Nick Carter, had given her the bruises. No word yet on where this new bruises came from. Anyone have any ideas?!?
