Ke$ha has completed her stint in rehab to treat an eating disorder. She said she’s working on music and she’s happy to be back.

She first took to Twitter to post a photo of herself with red hair, looking outside of a window on a plane. “Meow,” she wrote.

She then wrote, “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.”

She ended the tweets with, “life is beautiful. I'm so blessed to have u all.”

As we previously reported, the “Tik Tok” singer, 26, entered rehab in early January. She revealed at the time that she was struggling with eating disorders and that she was seeking treatment to get better.

She never planned on being in rehab for any definite amount of time. A friend told People of her surprise return, "I had no idea she would be out today," adding, she “really had no timeline" for how long she would stay.

Ke$ha will be returning to work but she won’t be performing this spring as planned. Last month she announced she would be canceling a string of shows to focus more on her recovery.
