Amanda Bynes: I have no clue why people say I'm insane

Amanda Bynes has chronicled her bizarre antics with tweets and photos, and now she’s firing back at those calling her crazy.

“I have no clue [why people say I’m insane],” Bynes told In Touch magazine in a recent interview. “Every time I’ve heard it, it came from an ugly person’s mouth, so I don’t care. The only ones lying about me having a mental illness are people I don’t talk to.”

Bynes, 27, also said she doesn’t drink or smoke pot and discussed her frequent gym trips and complaints about her weight, which she chronicles on Twitter.

“I like being 100 pounds — 21 to go,” she tweeted along with a photo of her in her underwear.
