Kesha won't be touring again till she's fully turned her life right round.
The pop star, who checked into a Chicago rehab facility on Jan. 3, announced Tuesday that she has opted to extend her stay in treatment and therefore has scrapped her tour dates that were scheduled for March and April.
"I was so looking forward to performing at these dates but I need to follow my Doctor's advice and get my health back on track," said the "Timber" singer. "All of your support has been so amazing. I couldn't have done this without you all. I look forward to coming back stronger than ever on the next tour."
The statement released by her camp noted that ticketholders should consult their local box offices for refund information.
Meanwhile, a source tells E! News that Ke$ha is "doing great. Instead of cutting it to 30 days in treatment she has decided to stay a little longer. She has postponed a couple of days but is doing great."
Ke$ha, who freely revealed that she was being treated for an eating disorder when she first checked in, posted a note on her Facebook (she's maintained more of a presence on social media than most while otherwise off the grid) on Jan. 4.
"I'm a crusader for being yourself and loving yourself but I've found it hard to practice," the post read. "I'll be unavailable for the next 30 days, seeking treatment for my eating disorder ... to learn to love myself again. Exactly as I am. - k"
The singer's mom, Pebe Sebert, then checked into the same facility the following week for "post-traumatic stress disorder," at her daughter's behest, she said.
