Ke$ha thanks fans for continued support from rehab

Pop star Ke$Ha has reached out to fans online to thank them for their well wishes as she continues to battle an eating disorder in rehab.

The Tik Tok hitmaker checked into the Timberline Knolls clinic in Illinois to receive treatment just after the new year (14), and she has asked a friend to convey her gratitude for her devotees' continued support in a message on her Twitter.com page.

The note, posted online on Tuesday (21Jan14), reads: "This is Kesha's friend. She asked me to tweet an update for her because she doesn't have access to twitter right now. she says 'THANK YOU. SOOO MUCH. I'm overwhelmed to tears by all of the love, letters, and support!! I'll be back soon and better than ever.'"

Ke$ha's mom, Pebe Sebert, recently revealed her daughter, who has struggled with anorexia and bulimia for years, had been gravely ill when she turned to professionals for help and could have died if she had waited any longer to seek treatment.

She told People magazine, "(Doctors) told me her blood pressure and sodium were so low they'd never seen that, except with someone who'd had a heart attack. They'd said it was a miracle she hadn't already dropped dead onstage."

Sebert subsequently joined Ke$ha as a patient in the same medical center in a bid to deal with post-traumatic stress disorder.
