Ke$ha has left rehab and is feeling "healthy."

The "Timber" hitmaker has finished her treatment for an eating disorder at the Timberline Knolls clinic near Chicago and claims she's "happy" to be working on new music.

She took to Twitter last night to update her fans on her progress, writing, "Happy to be back! Feeling healthy & working on tons of new music, I can't thank my fans enough for all the love & support u have given me [sic]." She later added, "Life is beautiful. I'm so blessed to have u all [sic]."

The 27-year-old singer recently postponed her upcoming Warrior world tour, which would see her perform in Hammond, Indiana, on March 15 and Green Bay, Wisconsin, on April 13, following doctor's orders to overcome her issues before focusing on her career again. "I was so looking forward to performing at these dates but I need to follow my doctor's advice and get my health back on track ... I couldn't have done this without you all. I look forward to coming back stronger than ever on the next tour," she previously said.
