As you may already know, producer Dr. Luke aka Lukas Gottwald is bringing a case against his former protege Kesha for defamation of character.
It's one of many threads in a sprawling and complicated legal battle between the two, but now other artists are being drawn into it - most notably, Lady Gaga.
Gottwald filed papers on Friday that demanded Gaga (who has openly supported Kesha throughout the process') set a date for her deposition, after his lawyers claimed that she joined Kesha's 'smear campaign' against him and helped 'spread negative messages' against him.
His lawyers wrote 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, a deposition date from Lady Gaga."
Reps for Lady Gaga, meanwhile, issued the below statement: "As Lady Gaga's legal team will present to the court, she has provided all of the relevant information in her possession and is at most an ancillary witness in this process. Dr. Luke's team is attempting to manipulate the truth and draw press attention to their case by exaggerating Lady Gaga's role and falsely accusing her of dodging reasonable requests."
