Can You Tweet Star Power?

Actress Katherine Heigl is suing drugstore chain Duane Reade because they tweeted a photograph of her exiting a store, bags of stuff in her hands. They used her handle and said she can't resist shopping there.

Is the store allowed to send that image into the social media world? Is she fair game since she is in public? Can they make that statement as well?

Is the store taking advantage of her star power to market their goods? Is there anything wrong with that?

Is this an unauthorized use of her likeness or is it just a silly tweet of a paparazzi photo, with a silly caption?

Here's the next big question for you: if you retweet the post, can you be sued as well?
