Hayley Williams Topless Photo Leaks

Musician Hayley Williams of Paramore arrives to the 2009 MTV Video Music Awards at Radio City Music Hall on September 13, 2009 in New York City.

Hayley Williams is at the center of an Internet scandal after a topless photo of the Paramore frontwoman was posted to Twitter.

The picture, which features the 21-year-old singer looking into the camera with her shirt pulled down over her chest, appears to have been taken by Williams herself. It was posted to her Twitter account late Thursday night, allegedly unbeknownst to the flame-haired singer.

"Well ... My night just changed drastically," Williams tweeted in response. "Got hacked."

Despite its prompt deletion, the photo quickly spread across blogs and media sites, with Paramore fans gathering on Twitter to show support.

The scandal comes at an otherwise good time for the singer - she is featured on B.o.B's "Airplanes," which has reached No. 2 on Billboard's Digital Songs chart, and Paramore is set to join Tegan & Sara and New Found Glory (the band of Williams' boyfriend, Chad Gilbert) on this summer's Honda Civic Tour.

Williams has yet to comment further on the incident.
