Ke$ha has checked into rehab to treat an eating disorder.

The Tik Tok singer said in a statement provided by her spokesman Friday that she'll be unavailable for the next 30 days while she seeks treatment for an undisclosed eating disorder.

"I'm a crusader for being yourself and loving yourself, but I've found it hard to practice," she said.

The 26-year-old vegetarian pop star said she wants to "learn to love myself again, exactly as I am." No other details were provided.

Ke$ha, whose real name is Kesha Rose Sebert, is the performer of such tunes as Crazy Love, Die Young and Timber with Pitbull. She starred in the MTV reality series My Crazy Beautiful Life.
