Jennifer Lopez

J.Lo already had a protective order against John Dubis for contacting her mother when he made an even bolder infringement upon her personal life. Dubis, uninvited, moved into the singer's pool house and updated Facebook with pictures of himself on her property. He managed to stay out of her security's way for several days before police apprehended him.
