Singer Ke$ha has checked in to Timberline Knolls rehab center near Chicago for issues with her weight.
TMZ reports that this is also the same place Demi Lovato went for her issues. Ke$ha reportedly is blaming producer Dr. Luke — claiming he called her a fat refrigerator. TMZ sources directly connected to Ke$ha told the website that Dr. Luke slammed the singer over the weight she had gained in her downtime post tour. Ke$ha says Luke — a huge producer who has worked with Miley Cyrus and Rihanna — began calling Ke$ha fat and urged her management team to do something about it.
