Despite caring for her brood of children, Angelina Jolie somehow found time to ink in the latitudinal and longitudinal coordinates for Nice, France, the birthplace of her and Brad Pitt's twin babies, Knox and Vivienne. Their birthplaces are located right below the global coordinates for the birthplaces of Maddox, Shiloh, Zahara and Pax. But they also leave lots of arm space for more birth tatts to come. This got us remembering back when her arm was originally decorated with just a Chinese dragon, which was later topped with "Billy Bob," the name of her second husband, actor Billy Bob Thornton. The unfortunate latter was unceremoniously removed after her swift divorce from Thornton. And the dragon was later lasered off to make room for babies. Anyway, that got us thinking about how many celebs have tattoos. There are a lot. But not just the ones you normally think of with very prominent ink, like Tommy Lee's full sleeves, Pink's eclectic collection, Nicole Richie's baby back wings, Eve's paw prints and Diablo Cody's pinup queen. Turns out there are also stars who have more discreet ink. Take a look at this Celebrity Ink Rink photo gallery and you may surprised by who has stars, flowers, crosses and angels hidden on their tummies, backs, wrists, necks and ankles.
