Ke$ha is seeking treatment for an eating disorder. The "Timber" singer, 26, checked into rehab on Friday, Jan. 3.

"I'm a crusader for being yourself and loving yourself, but I've found it hard to practice," the "Crazy Kids" crooner told Us Weekly 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."

She is reportedly at Timberline Knolls rehab center -- the same residential treatment center in Illinois that Demi Lovato checked into back in 2010.

Just one day before, Ke$ha posted a Twitter picture of herself getting a new tattoo of a smiley face. "Happy new year!!!! get it?" she wrote. 

On New Year's Day, the singer debuted her "Dirty Love" music video, which was also K$ha's directorial debut. "This is my face song off my record," the Warrior hitmaker tweeted.

"Cheers to this year being the best year ever," she wrote. "2014 gon be the year of truth and freedom."
