Pop star Ke$Ha has entered rehab to address an eating disorder.
Sources tells Tmz.com the outlandish Tik Tok singer has checked in to the Timberline Knolls clinic in Illinois, where Demi Lovato spent three months tackling addiction issues and her own eating disorder in 2010 and 2011.
Confirming the news in a statement, Ke$ha says, "I'm a crusader for being yourself and loving yourself, but I've found it hard to practice. 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."
Many ticket-holders couldn't get into the O2 Arena show on Tuesday night (September 19th) because they didn't bring photo ID to match their booking.
An album re-release, a new song and a documentary mark the singer's legacy this year.
The actor plays the titular hero in the forthcoming adaptation.
