Katy Perry pierced her own nose

London: Singer Katy Perry says she pierced her nose with a safety pin in her mother`s absence and regrets doing so because she still has a horrible scar. "I asked my mother permission so I could get my nose pierced. And of course she didn`t give it to me, she said, `It was ridiculous and she wasn`t gonna do that.` So she then went on an errand, so I took a safety pin and a piece of ice and I pierced my own nose," Perry said during an appearance on a TV show, reports starpulse.com. "She saw it later, she`s like, `Oh it`s not as bad as I thought.` Because it was just a little diamond. But I still have this horrible scar that everybody brings up when they get really close," added the 27-year-old. IANS
