Justin Bieber is the latest celeb to get his neck inked. Less than two weeks after he swore he was done with tattoos for a while, he showed off his newest piece on his neck, right under his earlobe. He joins the company of other ink-happy Hollywood stars, like Ariana Grande, who got the back of her neck tatted, and Chris Brown, who actually has most of his neck inked up. Adele also has a neck tattoo, right behind her right ear. Which celeb rocks the neck ink best?
