Just days after a New York Supreme Court judge denied Kesha's request to be let out of her Sony Music contract, citing a lack of evidence to the singer's claims of abuse and sexual assault by producer Lukasz "Dr. Luke" Gottwald, footage from a 2011 deposition surfaced showing Kesha denying those same allegations.

Now, Kesha's attorney is firing back against the leaked footage in a new statement to ET.

"Dr. Luke threatened her and her mother ... only after going to rehab and undergoing intense therapy was Kesha strong enough to stand up to this monster," her attorney, Mark Geragos said.

ET obtained the footage, which has been heavily edited. At one point, Kesha specifically says: "Dr. Luke never made sexual advances at me." Responding to questions regarding whether she and Gottwald had ever engaged in "intimate relations," or whether he had offered her a "roofie," Kesha responds with "No" on both accounts.

In a separate 2011 deposition, Kesha's mother, Pebe Sebert, also responds "No" to three questions regarding whether she had heard about her daughter having sexual relations, being date raped, or being drugged by Dr. Luke.

Dr. Luke's attorney, Christine Lepera, issued the following statement to ET regarding the video: "Tellingly, Kesha continues to evade the under oath sworn testimony of no abuse from her and her mother -- and the video of their testimony speaks a thousand words."

Dr. Luke has denied the allegations against him from the very beginning.

Back in 2014, when news of the past deposition first came to light amid Kesha's lawsuit, her attorney had this to say:

"Luke's latest legal maneuver comes as no surprise; it's a desperate Hail Mary and a pathetic attempt to once again blame his victim. He threatened to destroy Kesha's life and the lives of her family if she didn't cover up his sexual assaults in a 2011 deposition; Luke is now following through on his threats. Unfortunately protecting abusers out of fear happens all too often with battered women. This case is about Luke's physical, emotional and psychological abuse of Kesha and her fight to get him out of her life. After being driven to the brink of death and into rehab, she's no longer going to allow herself to wither away at the hands of her abuser as he tries to blame the victim."

In the aftermath of the judge's recent decision against Kesha, the singer has cancelled her upcoming performance at Loyola University Chicago, according to the institution's Department of Programming.

According to the announcement, "Kesha will no longer be able to perform … due to personal reasons."

"Kesha has expressed her disappointment in having to cancel, but she feels that this is the best decision for her at this time," the statement continued. "We respect her decision and wish her well." Students with tickets to her Friday concert will be issued full refunds.

Despite setbacks in court, Kesha has been receiving a wave of love and support from her fans and fellow music stars who have come out to stand behind the singer during this difficult time. Most recently, Taylor Swift donated $250,000 to the singer and Adele offered her public support while accepting a Brit Award.
