New York-raised Dr. Luke has some serious hits under his belt. The SONY producer was a part of making Kelly Clarkson 's "Since U Been Gone", Katy Perry 's "I Kissed a Girl" and "Roar," Avril Lavigne 's "Girlfriend," and Miley Cyrus ' "Wrecking Ball." All of these songs have been stuck in listeners heads, and have sold millions of copies. Dr. Luke may be one of the most successful music minds in the business. But now's he facing a civil lawsuit from his former protege Kesha, who claims Dr. Luke sexually assaulted, emotionally abused, and even drugged her. While the producer has left most of the talking to his attorneys, he did take to Twitter recently to say that he did not rape Kesha and thinks of her like his little sister. Dr. Luke claims that up until the lawsuit, the two were friends.
