Good for you, Ke$ha! The pop star is taking her rehab seriously — postponing her tour dates to March and April. Her rehab is for her eating disorder that she’s been fighting. Her people say that she pushed back her tour dates so she can be committed to the treatment. Her facility is the same place that treated Demi Lovato successfully. At first she was planning to undergo a 30-day treatment, but now it’s going to be 34 days. Best of luck!
