2. RIHANNA

Growing up, Rihanna's father was a drug addict. Although they've had a strained relationship, RiRi has talked about how she has tried to fix their connection. After the Chris Brown incident, Ronald Fenty, her pops, went to the press to discuss the abuse, without actually talking to Rihanna. He went to the media, got a check, and, according to his daughter, didn't even call to see if she was still alive. What a guy.
