According to court documents obtained by ET, the lawsuit was filed in a federal court in Tennessee on Wednesday. Dr. Luke (real name: Lukasz Gottwald) claims that Sebert has "continued to publicly defame him" by "consistently" using "her Twitter page to publicize her baseless allegations that Gottwald purportedly abused her daughter" and encouraging "Kesha's fans to rally against" him. He also claims Sebert made false accusations in an interview
published on March 10, 2016, in Billboard
Sebert was previously sued by Dr. Luke for defamation in October 2014.
"This marks Dr. Luke's second effort to sue a mother for publicly supporting and believing her daughter about being raped," Alex Little, attorney for Sebert, tells ET in a statement. "It's also a transparent attempt to delay the trial of these issues. Mrs. Sebert looks forward to presenting her case to a jury as soon as possible. When the evidence is made public, she expects the jury will conclude that all of her statements have been justified."
Dr. Luke's lawyer, Christine Lepera, released the following statement to ET:
"After we originally filed suit against Pebe Sebert, she continued to make outrageous, false and defamatory statements against Dr. Luke in her widespread media campaign to damage him and smear his name.
Pebe Sebert's lawyers flat out refused to allow us to add those statements to the existing case or to toll the statute of limitations on them --- so we've been compelled to file an additional action."
As ET previously reported, after nearly four years of fighting a contentious legal battle in California, Kesha dropped her sexual assault lawsuit
against the producer last month in an effort to focus on creating new music, according to her legal counsel. She is, however, maintaining her lawsuit against Dr. Luke in New York.
"Kesha has dismissed her California action without prejudice while she pursues her appeal and other legal claims in the New York courts," Daniel Petrocelli, a member of Kesha's legal team, explained in a statement to ET.
"Kesha is focused on getting back to work and has delivered 28 new songs to the record label," Petrocelli continued. "We have conveyed to Sony Music and the label Kesha’s strong desire to release the single and an album as soon as possible."
