Amanda Bynes Tweets Topless Photos, Denies She's 'Mentally Insane'

Whether she was pining away for Drake, lashing out at the tabloids or shaving half her head, Amanda Bynes was at the center of attention for most of April.

The actress kicked off the new month in similar fashion Wednesday, posting a thread of sexy topless photos to her Twitter, and we've got the shots for you right here on RadarOnline.com.

"Rawr," the What I Like About You star, 27, tweeted with one of the pics; in the other -- in which strands of her blonde hair obscure her bare breasts from camera view -- she wrote, "Long hair don't care."

The former Nickelodeon star responded to rumors she's "mentally insane," telling InTouch that the only individuals spreading that rumor are "people I don't talk to."

Asked if she has any addictions, Bynes said she does not indulge in booze or pot, and that any funny-looking cigarettes she's been snapped with contain only tobacco.

Bynes told the magazine she's financially set for life, and looking forward to starting her own fashion line, as well taking her music career further.

"I'll design clothes and sing because I want to, not because I need the money," she said. "I love singing and I can't wait to start working on an album. Right now, I'm getting in shape for all of the photos shoots."

Maybe Amanda wants to challenge Mila Kunis, who was just named the sexiest woman in the world by FHM magazine. Details in the video below.
