LUKASZ “Dr. Luke” Gottwald’s legal team subpoenaed Lady Gaga as part of the producer’s defamation lawsuit against Kesha, who has, in her own lawsuit, accused Dr. Luke of sexual assault.

“In connection with Dr. Luke’s defamation claims against Kesha, various third parties are being deposed by both sides, including celebrities,” Gottwald’s rep said in a statement.

“Dr. Luke’s counsel served a subpoena on Lady Gaga because she has relevant information regarding, among other things, false statements about Dr. Luke made to her by Kesha. This motion has become necessary because Dr. Luke’s counsel has not been able to obtain, despite repeated request[s], a deposition date from Lady Gaga.”

Representatives for Lady Gaga and Kesha did not respond to Rolling Stone’s request for comment.

Lady Gaga has been one of Kesha’s most vocal supporters during the “Tik Tok” singer’s arduous legal battle with Dr. Luke, who Kesha initially sued in 2014 in an attempt to void her contract with the producer’s Kemosabe Records. When Kesha’s lawsuit was first filed, she accused Dr. Luke of “sexually, physically, verbally, and emotionally” abusing her.

Gottwald, who denied all accusations, responded with his own countersuit accusing Kesha of defamation.

After a New York judge denied Kesha’s injunction that would have severed her professional relationship with Dr. Luke, Gaga turned to social media to reiterate her support for Kesha.

“The very reason women don’t speak up for years is the fear that no one will believe them or their abuser has threatened their life or life of their loved ones/livelihood in order to keep their victim quiet and under control,” Gaga wrote at the time. “What happened to Kesha has happened to many female artists, including myself, and it will affect her for the rest of her life.”
