Everyone's just suing and countersuing all willy-nilly now in the Dr. Luke/Kesha sex abuse standoff, with Lady Gaga dragged into the mess as a potential witness in at least two civil suits. Hope she likes depositions :(

Mark Geragos, the lawyer representing Kesha in her sexual assault claim against super-producer Lukasz "Dr. Luke" Gottwald, claimed on Twitter yesterday that Luke was also the record producer who raped Lady Gaga when she was 19.
