Pop star Kesha's former music producer has hit back at a "trial by Twitter" social media campaign against him, which has been backed by some of the biggest names in the music industry.
Anger and sympathy for Kesha has swelled after a New York judge ruled on Friday that Kesha, 28, could not be released from her recording contract with Sony Music despite filing a sexual assault lawsuit in 2014 against her producer and former mentor, Dr Luke.
Taylor Swift on Sunday donated US$250,000 (NZ$515,968) to the Tik Tok singer while Lady Gaga, Kelly Clarkson, Miley Cyrus and Ariana Grande are among hundreds who have posted messages on Instagram and Twitter to the fast-growing #FreeKesha campaign.
"Most important for Kesha, is that these beautiful, powerful women are standing behind her, letting the world see how powerful the truth is!" Kesha's mother, Pebe Sebert, posted on Twitter on Sunday, after announcing the donation from Swift.
Swift's representative confirmed the pop star had donated US$250,000 to "meet any of the singer's financial needs."
Dr Luke's lawyer, Christine Lepera, on Monday again denied Kesha's allegations of rape and emotional abuse and accused the singer and her legal team of conducting a "trial by Twitter, using a vicious smear campaign to ruin his reputation."
She said the allegations in Kesha's lawsuit are "outright lies that have been advanced to extort a contract renegotiation and money."
Dr Luke countersued in 2014 and both cases have yet to come to trial.
The Producer broke his silence on Tuesday, taking to Twitter to voice his innocence, claiming Kesha was "like my little sister".
"Until now I haven't commented on the lawsuits, which should be resolved in court not here on Twitter," he said.
"It's a shame that there's so much speculation out there basing itself on so little information."
"I didn't rape Kesha and I have never had sex with her. Kesha and I were friends for many years and she was like my little sister."
Dr Luke claimed Kesha had denied under oath the allegations, tweeting a grab of an article titled focusing on the singer's 2011 testimony.
"Kesha has denied under oath the horrible allegations now being made against me," Dr Luke said.
"I have 3 sisters, a daughter and a son with my girlfriend and a feminist mom who raised me right."
"It is sad that she (Kesha) would turn a contract negotiation into something so horrendous and untrue."
Lepera said Kesha, who burst on the music scene in 2009, was "already 'free' to record and release music without working with Dr Luke as a producer if she doesn't want to."
"Any claim that she isn't 'free' is a myth," Lepera said.
