LATEST: Katy Perry has hit back at her controversial knife snap, insisting she is "against all violence"
The I Kissed A Girl was pictured earlier this week (22Oct08) holding a blade up to her face in a promotional picture taken for her album, One For The Boys.
Anti-crime protesters in Britain slammed the star, branding her "out of her mind" and "unacceptable".
But a representative for Perry has defended her decision to pose with the knife, telling MTV News, "Katy Perry is against all violence. The photo in question was taken in 2005 and is in no way related to the current events in the U.K."
And Fall Out Boy star Pete Wentz has also stood up for Perry's posed snap, saying, "It's not just because Katy's boyfriend Travis (MCCoy) is my dude, but it's absolutely ridiculous to compare that photo to somebody promoting violence."
