Dr. Luke wasn't wrong...
He told her she was overweight, not very pretty and most of all untalented. To be honest she really was all of those things. Seeing her ''bikini candids'' years ago was shocking, she was grossly overweight for a female pop star. The fact that she had near zero vocal talent made it even worse.
Why was she famous? she's lucky she was given the chances she had. The man was completely honest with her about her situation. I feel like that is why she keeps trying to attack him legally.
