Ke$ha completes rehab, 'feeling healthy'

Pop star Ke$ha has completed her two-month treatment at a rehab facility for an eating disorder and is back on the scene.

She was spotted at LAX sporting rainbow-hued hair and smiling.

She tweeted to her 3.5 million fans last night about her release and sunny outlook. "Happy to be back! Feeling healthy & working on tons of new music," she wrote. "I can't thank my fans enough for all the love & support u have given me❤️️. Life is beautiful. I'm so blessed to have u all."

The singer checked into rehab just after the New Year and said in a statement at the time, "I'm a crusader for being yourself and loving yourself, but I've found it hard to practice."
