Kesha got a loud show of support on her way into the NYC courtroom for her legal face off with Dr. Luke.
A few dozen fans chanted "Free Kesha" and held up signs as she walked in Friday morning. Some of the signs featured brutal commentary about Kesha's longtime producer, such as ... "Dr. Luke is a piece of s***t."
Kesha is suing Dr. Luke to get out of her contract, and has accused him of sexually and verbally abusing her for years.
Luke's denied the allegations and filed a countersuit against Kesha and her mother.
