Several months before going public with claims she'd been sexually assaulted by Dr. Luke, Kesha wrote a series of letters to fans revealing her "torturous" abuse.
According to Buzzfeed, the 27-year-old replied to fans on pages of a children's colouring book, while being treated in rehab for her eating disorder in January.
Specifically referring to Dr. Luke as her abuser, Kesha wrote to one fan: "Dr. Luke has tortured me and my family. He did do what people know about and so much more terrible s---."

In a second letter, the singer pinpoints the 41-year-old producer once again, saying: "These music business a------ (well, Dr. Luke) had almost successfully crushed my magic."
A third letter sees Kesha referring to her eating disorder, claiming that Dr. Luke was the cause of her ongoing battle.
"Someone I work with has literally driven me into this disease, tortured me and f----- with me and my family," she wrote.
Only last week, Kesha filed a lawsuit against Dr. Luke, claiming he had "sexually, physically, verbally and emotionally" abused her over a ten-year period.
Days later, it was revealed that Kesha's mum had allegedly threatened via email to go public with the rape allegations, if Luke did not revoke her daughter's contract.
According to TMZ, the email stated: "We, me and Kesha and her friends… like Lady Gaga, are going to make all of this really PUBLIC, in the next few days. Luke date raped Kesha when she was 18…
"Luke also gave Kesha pills. She ended up naked in his hotel room 2 days later. No longer a virgin? Do we all want this to come out? Either Luke releases Kesha from all legal contracts, and gives back all my publishing, or we, Kesha and I, tell the truth."
After Kesha's legal team filed their lawsuit, Dr Luke filed his own against the singer… claiming she was "lying to get out of her legally binding contract".
Dr. Luke, is responsible for all of Kesha's music and gave the singer her first record deal in 2005.
