Kesha (full name: Kesha Rose Sebert) is currently embroiled in a legal battle with her longtime producer Dr. Luke, whom she alleges drugged and raped her and verbally and emotionally abused her for years. Luke (born Lukasz Gottwald) vehemently denies the accusations and is countersuing for breach of contract and defamation.

Monday, Luke’s attorney, Christine Lepera, released a statement to PEOPLE following Kesha’s tweet to Gaga and Biden.

“Ms. Sebert, who in sworn videotaped testimony from 2011 stated that she had never been sexually abused or drugged by Dr. Luke, is neither a victim nor the appropriate person to be held up as an example for this important issue,” Lepera said.

Kesha’s lawyer, Mark Geragos, responded with a statement, saying: “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.”

Since her plea for a preliminary injunction that would allow her to record music outside of Luke’s purview was shot down by a New York Supreme Court judge on Feb. 19, celebrities (including Gaga) have taken to social media to support Kesha.

Hours before the ceremony, Gaga, 29, took to Twitter to reiterate her support for Kesha.

“@kesharose I’ll be thinking of u 2nite. This is not over we’ll stand by u until you are free to live a HAPPY life. Everyone deserves that,” she tweeted.
