After checking into a 30-day rehab program for an eating disorder back in January and subsequently extending her stay early last month, pop singer Ke$ha has announced that she's left the Chicago-area facility where she was seeking treatment.

Late last night the singer posted a pictured of herself looking out of the window of an airplane with the caption, "meow." Today, she tweeted she's "happy to be back" and "feeling healthy...working on tons of new music."

Early into Ke$ha's stay, her mother Pepe Sebert publicly claimed she believed her daughter's frequent collaboration Dr. Luke was to blame for Ke$ha's troubles. Sebert later, herself, checked into the same facility for post-traumatic stress disorder. No word on whether or not Dr. Luke is who Ke$ha is working on new music with now.
