The singer, 27, completed a two-month treatment program for an eating disorder. She arrived at Los Angeles International Airport Thursday with rainbow hair and a sweatshirt that read "Ima Survivor."
Ke$ha tweeted a picture of herself from the plane after landing. The "Timber" chart topper then told her 3.56 million Twitter followers, "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." After posting emoji hearts and a rainbow, the Nashville-raised musician tweeted, "Life is beautiful. I'm so blessed to have u all."

In February, Ke$ha extended her 30-day stay and postponed her spring tour to focus on getting "my health back on track," she told E! News in a statement. "All of your support has been so amazing. I couldn't have done this without you all. I look forward to coming back stronger than ever on the next tour." The concert dates, which were scheduled for March and April, have not yet been rescheduled.
When Ke$ha sought treatment in January, the pop star told E! News in a statement, "I'm a crusader for being yourself and loving yourself but I've found it hard to practice." Her mother, Pebe Sebert, later entered the same Chicago-area treatment facility to seek help for post-traumatic stress disorder.
Ke$ha's pop peer Demi Lovato sought treatment for an eating disorder at Timberline Knolls in 2010. "I wish her the absolute best and I think she is doing a really great thing for herself," the 21-year-old told E! News in February. "It's really great when you take time out of a schedule that everybody wants you. There are so many things, you work so hard and then you kind of forget about yourself, and you don't really get to treat the things that everyone has like stress. You just kind of throw yourself into work."
The "Neon Lights" singer added, "When I took that experience, I needed it to live. It taught me a lot and it helped me a ton. I wish her the absolute best. She's a really sweet girl and she's going to be fine."
