Kesha announced last week that she is suing her producer Dr. Luke, a.k.a. Lukasz Gottwald, for sexual assault, with Kesha’s lawyer alleging that the singer suffered years of “mental manipulation [and] emotional abuse†at the hands of her mentor. Dr. Luke responded in turn with a countersuit accusing Kesha of trying to extort him. Today, new evidence has emerged in the form of a 2011 deposition obtained by TMZ (and unsealed after a request from Dr. Luke’s lawyer) that reveals that Kesha previously swore under oath that Dr. Luke never drugged her and that the pair never engaged in sexual relations. In response, Kesha’s lawyer Mark Geragos told TMZ that unsealing the deposition was “a pathetic attempt to once again blame the victim†and that she lied initially because Dr. Luke “threatened to destroy Kesha’s life and the lives of her family if she didn’t cover up his sexual assaults.†And so the sordid back-and-forth continues.
