Lawyers for the disgraced music producer, who has been in court with his former protegee Kesha since 2014 after she accused him of sexually and verbally abusing her, claim they were forced to subpoena the "Born This Way" singer following several unsuccessful attempts to get her formal testimony on the record.
"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," his lawyer said in a statement to Variety Saturday. "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."
Last year, text exchanges between Gaga and Kesha were submitted to the courts as evidence, but the judge sealed the messages, making the content confidential.
Now that the subpoena has been issued, Gaga will be required to set a date to appear in-person for a three-hour deposition, during which she'll be quizzed by Dr. Luke's attorneys.
She may not be the only celebrity taking the stand in the near future: “In connection with Dr. Luke’s defamation claims against Kesha, various third parties are being deposed by both sides, including celebrities,” his lawyers confirmed in the statement.
Lady Gaga has been a public supporter of her friend Kesha throughout the "Tik Tok" singer's legal battle against Dr. Luke.
