One of the most significant challenges Kesha faced was her highly publicized feud with her former producer and mentor, Dr. Luke. In 2014, Kesha filed a lawsuit against Dr. Luke, alleging emotional distress, physical abuse, and sexual battery.

Kesha's experience highlights the darker side of the entertainment industry, where artists, particularly women, are often vulnerable to exploitation and abuse.
