Amanda Bynes Says She Has Eating Disorder

Troubled actress Amanda Bynes says she's not mentally ill.

"I have an eating disorder," she just tweeted.

The former Disney star and Easy A actress sent the tweets after photographers caught her wandering around Times Square looking like a homeless person on her 27th birthday with a hood pulled over her head and wearing flip flops.

"I moved to New York City and I love it," she tweeted: "I lost 4lbs since I moved. I'm 121lbs. My goal is 100lbs."

She writes that she has a "hard time staying thin."

She recently tweeted a photo showing off piercings in her cheeks. No wonder her friends areĀ  reportedly concerned.
