Singer Katy Perry has got her nose pierced to cover a scar.

The 29-year-old got a stud punched through her nostril in the hope of covering up the scar she was left with at the age of 13 when she poked a hole in her nose herself with a safety pin and an ice cube, reports contactmusic.com.

She posted a video of the procedure on Instagram and she is seen crying in pain.

Her nervous cry unsettled the trained piercer as he can be heard saying: "I know, I'm sorry! Don't say anything. You're making me hurt."

She accompanied the footage with the caption: "Last time I did this I was on my own with a safety pin and cube of ice @ 13. This time I thought it was best I left it to the pro's. Sorry mom (again) (sic)."
