(Photo by Dan Steinberg/Invision/AP) (Newser) – While some celebs may later come to regret their tattoos, piercings have the advantage of being removable—or hidden under a costume. From Cameron Diaz's nose to Neil Patrick Harris' nipples, below are 11 A-listers who've gone under the piercing gun: Cameron Diaz: The recently married actress debuted a nose ring last month, making some think that her musician husband's rocker style is rubbing off on her. Rooney Mara: For her role in The Girl With the Dragon Tattoo, the actress got her nipple pierced in order to play the edgy Lisbeth Salander. Harrison Ford: Not only does the 72-year-old actor sport a piercing in his left earlobe (the result of a trip to Claire's Accessories for his 55th birthday), but he even pierced Jimmy Fallon's ear during an appearance on Late Night in 2013. Drew Barrymore: The actress's piercing is only visible when she opens her mouth wide. Beyonce: When the singer showed off her bellybutton ring on the cover of Shape magazine, some wondered if she might bring back the '90s trend. (Remember when every pop star had one?) Shia LaBeouf: Earlier this year, the actor was spotted with a pierced eyebrow and a 'rattail' hair-do. Neil Patrick Harris: If it wasn't for his shirtless get-up at a Playboy Halloween party in 2012, the world may never have known about Neil's nipple piercing. Lady Gaga: The pop singer reportedly had a wardrobe malfunction in 2011 that showed off her genital piercing to paparazzi. Keira Knightley: She may frequently act in period films, but the actress has a more modern bellybutton piercing. Will Smith: The 46-year-old action star is frequently seen wearing earrings in both ears. Kylie Jenner: Bruce Jenner reportedly had a meltdown earlier this year when he learned that his youngest daughter had gotten her nipples pierced.
