Luke has responded to allegations in a series of tweets.
The allegations echo the tone in a since-dismissed lawsuit Luke filed against Kesha's lawyer, Mark Geragos, and Kesha's mother, Pebe Sebert, that alleged extortion.
Luke then critizcizes those tweeting in support of Kesha, claiming they are not fully informed.
Gottwald included screenshots of TMZ and New York Daily News reports of testimonies from Kesha.

"Kesha's lawyer Mark Geragos made another false rape claim against me that was denied by publicly by Lady Gaga," Luke tweeted, followed by another screenshot of a TMZ story.
Luke ended his series of tweets by thanking his supporters.
This is the first time the producer has directly commented on the allegations since they emerged publicly two years ago.
The lawsuit has drawn many celebrities to support Kesha with #FreeKesha across Twitter.
Taylor Swift donated $250,000 to help with Kesha's legal fees.
