Dr Luke's lawyers have slammed Kesha's "outright lies".
The 'Tik Tok' singer was denied permission to leave her recording contract with the producer on Friday (19.02.16), and the music mogul's legal representatives have criticised her for engaging in "trial by Twitter", with her allegations of sexual abuse all part of a "vicious smear campaign to ruin Luke's reputation", TMZ reports.
The lawyers went on to claim the 28-year-old star's "lies" were designed "to extort a contract renegotiation and money."
However, the lawyers also insisted Kesha is "free" to record with Luke or any other Sony producer, and that, having invested $11 million in her career, they are "committed to continuing to promote her work."
Following the court verdict, which saw Kesha break down in tears, the singer has thanked fans for their support in her legal battle.
She tweeted: "thank you for all the support in my legal case animals. i love all of you. it's meant the world to me. xoxo (sic)"
A host of female stars, including Lily Allen, Lady Gaga, Ariana Grande and Lorde, have tweeted messages backing Kesha, while Taylor Swift has donated $250,000 to the 'We R Who We R' hitmaker.
