Kesha has said she is feeling "blessed" after leaving rehab.
The Crazy Kids singer entered a centre in Chicago in January to treat an eating disorder.
She has now left the facility after several weeks of treatment and posted a message on Twitter telling fans she is on the mend.
She shared a picture of a redhead looking out of a plane window, thought to be herself, and an hour later wrote: "Happy to be back! Feeling healthy & working on tons of new music. I can't thank my fans enough for all the love & support u have given me."
Kesha, 26, then posted a string of hearts and went on: "Life is beautiful. I'm so blessed to have u all."
The Tik Tok singer was forced to postpone dates on her US tour so she could continue receiving treatment.
At the time she promised her fans she would be "coming back stronger than ever on the next tour".
