The drugs and party girl rep are rumours and heresay. If true, what happens out of hours is her own business.
As for the pictures- the girl is the victim. Her trust has been violated. She didnt ask for this. To be fired for being taken advantage of is downright wrong, and victim blaming/shaming.
I wouldn't be surprised if her supposed reputation is being used as a reason why its 'OK' to share the picture- she deserved this, she's a dirty little ****.
