The "Timber" singer reportedly checked in to Timberline Knolls on January 3, saying in a statement to E! News that she will be spending 30 days there in an effort to "learn to love" herself again.
Her mother, Pebe Sebert (who is now being treated at the same facility for post-traumatic stress disorder) revealed that Ke$ha had a lot of pressure on her when it came to her weight.
Her music producer, Dr. Luke, apparently told her she looked like a "f**king refrigerator" during a music shoot in 2012 and her mom also revealed that she had an advisor who basically told her to do whatever it took to lose weight.
"She had an advisor who told her he had a meeting with a record company and they said she better lose 15 pounds in the next 30 days," Pebe revealed to RadarOnline. "He told her he didn't care if she shoved her hand down her throat or took illegal drugs, but she had to lose the weight."
Unfortunately, it looks like her backstage requests might give us a glimpse into just how serious the situation got.
According to a rider obtained by the same site, Ke$ha basically only had veggies and booze backstage.
As far as food, she requested: Vegetarian hand rolls without rice (no mayonnaise), one raw vegetable tray and one tray of streamed vegetables or dried veggie snacks from Whole Foods if possible.
She also asked for a bottle of tequila, two bottles of "nice" Cabernet and a bottle of vodka. In addition, she requested her own toilet, sink and shower as well as a lavender-scented candle.
Ke$ha is reportedly being treated for bulimia and despite speculation, her mom denies that the singer has a drinking problem.
We wish her all the best in her recovery.
