Pop star Ke$ha has reportedly checked into a rehab facility seeking a 30-day treatment for an undisclosed eating disorder.

Us Weekly reported that Ke$ha is at the Timberline Knolls Residential Treatment Center, southwest of Chicago, which is the same place where Demi Lovato, the American singer/actress, completed her treatment for an eating disorder and other health-related issues in 2010.

According to reports, the 23-year-old singer said in a statement on Friday: “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.”

The details of her eating disorder are yet to be disclosed.

In 2010, Ke$ha told the Phoenix New Times that she is a vegetarian, “I just love animals, and I’m an advocate for animal rights.”

The “Tik Tok” singer, whose real name is Kesha Rose Sebert, is featured in the recent music video “Timber” with rapper Pitbull. The song is No. 2 on Billboard’s Hot 100 singles chart. She also starred in the MTV reality series “My Crazy Beautiful Life.”
