London, February 9 : Katy Perry has been slammed by her Twitter fans after posting a raunchy photograph of an emerging teenager and calling her "fresh meat".

The I Kissed A Girl singer posted a photograph of the 17-year-old singer Sky Ferreira that showed the teen with her legs apart and just a water bottle preserving her modesty.

"I like em right before they're famous... Fresh meat," the Daily Star quoted Perry as saying on the popular micro-blogging website.

The remark left her followers reeling, with many accusing the songbird of stooping low.

One fan wrote: "What's going on Katy? What's happened to your class?"

Another added: "Shame on you Katy Perry for contributing to a minor?? Thought you were cool but I see YOU ARE NOT!! That could be my kid?? Not a Class Act in my book!"

Even Perry's showbiz blogger pal Perez Hilton wrote: "She can't be a hot mess already! She's not even 18!"
