Katy Perry took to Instagram on Friday to upload a video of her getting her nose pierced. "Last time I did this I was on my own with a safety pin & cube of ice @ 13," she captioned the post. "This time I thought it was best I left it to the pro's. Sorry mom (again)." In the short clip, the 29-year-old pop star can be seen laying on a table as a needle goes through her nose. Not surprisingly, she then shouts, "Ow!"
