Another day, another sultry picture from Amanda Bynes. After posting a picture of herself in a lacy black bra, the former Nickelodeon sweetheart has now posted topless photos of herself on Twitter.

Amanda only had her hair and arms to cover her breasts while she took her pictures without a top on. The rest of her wardrobe during her personal photo shoot consisted of a black lingerie bottom and torn fishnet black stockings.

The 27-year-old ex-child actress has been posting self-shot portraits of herself on Twitter lately. She has also been lashing out at media outlets that have questioned her sanity. At one time she threatened everyone with a lawsuit for insinuating that she was mentally ill.

"I have no clue [why people say I'm insane]," she told In Touch Weekly. "Every time I've heard it, it came from an ugly person's mouth, so I don't care.

"The ones lying about me having a mental illness are people I don't talk to."

She insisted that she doesn't drink alcohol or smoke pot, contrary to other reports. She does, however, smoke tobacco.

Amanda made headlines last year when she got into one traffic-related lawsuit after another. She was charged with driving under the influence, hit-and-run, and driving with a suspended license in separate incidents.

She also sparked controversy with her alleged bizarre behaviour that included reportedly stripping down to her bra in her spin class and smoking in the locker room.

Amanda, who was recently given access to her millions, told the magazine that she will design clothes and sing "because I want to, not because I need the money."

She's currently retired from acting. Her last film was in 2010 when she appeared alongside Emma Stone in "Easy A."
