Ke$ha has entered rehab.
The 26-year-old singer is seeking treatment for an undisclosed eating disorder, according to E! News. Ke$ha, whose real name is Kesha Rose Sebert, entered rehab on Friday, Jan. 3.
"I'm a crusader for being yourself and loving yourself but I've found it hard to practice," the singer told the entertainment news outlet in a statement. "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."
The singer has not addressed the news on any of her social media profiles or on her website at the time of this writing. Earlier in the week she tweeted, "Cheers to this year being the best year ever. 2014 gon be the year of truth and freedom."
