Ke$ha’s Eating Disorder Was Caused By Dr. Luke Calling Her A ‘Refrigerator’?! Ke$ha has checked into rehab to treat an eating disorder. The "Tik Tok" singer said in a statement provided by her spokesman Friday that she'll be unavailable for the next 30 days while she seeks treatment for an undisclosed eating disorder. "I'm a crusader for being yourself and loving yourself, but I've found it hard to practice," she said. Apparently the 26-year-old singer has been fighting with Dr. Luke, from her record label, for awhile now! After Ke$ha’s 2011 Get Sleazy tour ended, Luke started harping on the singer to lose weight. Then, during a 2012 video shoot, he even told her she "looks like a f*cking refrigerator.” The 26-year-old vegetarian pop star said she wants to "learn to love myself again, exactly as I am." No other details were provided.
