Kesha has entered rehab to get treatment for an eating disorder.
In a statement provided by her spokesman on Friday, Kesha said she would be “unavailable for the next 30 days” as she sought treatment.
“I’m a crusader for being yourself and loving yourself, but I’ve found it hard to practice,” the singer added.
Kesha, 26, is being treated at the Timberline Knolls centre near Chicago.
She said she wanted to “learn to love myself again, exactly as I am”. No other details were released.
The vegetarian singer, whose full name is Kesha Rose Sebert and is also known as Ke$ha, rose to fame with her song Tik Tok.
