EXCLUSIVE: Celebrity Tattoo Artist Bang Bang Reveals All About Inking Rihanna, Selena Gomez and More

Celebrity tattoo artist Keith "Bang Bang" McCurdy is telling all in his new book, Bang Bang: My Life in Ink, with a foreword written by Rihanna as she recalls their first interaction. "I remember thinking, this guy is gangsta as f**k. He doesn't give a f**k about me -- he doesn't know who I am and that is brilliant. So that's why I wanted him to do my tattoo. I knew he wasn't going to try any funny sh*t or act crazy; he was just going to do my tattoo."

"She's one of those people who you just like immediately," Bang Bang writes of Selena Gomez. "I've done several tattoos on Selena, including one I've promised never to reveal. And no, I'm not spilling it here, either. I believe the first one I did was Roman numerals on the back of her neck. It's a tribute to an important family member. I'm not sure which one, and I figure if she wants anyone to know, she'll tell the story herself."

"How do you feel when you see girls who've copied your lion tattoo?" Bang Bang asks Cara Delevingne. "At first, I'm like, 'Aw sh*t, that's annoying.' It's a weird feeling. But I guess imitation is the best form of flattery, in a way. But it's sad because it's for life and it's quite important to me. I can't fault people for getting something beautiful on their body. So in that way it's cool, but at the same time, I hate it."

"Where a tattoo is placed is just as important as what it is, so we tried it in a bunch of different places," Bang Bang writes. "We had originally thought we wanted two guns -- one on the front of each of her shoulders, just above the armpit area. But when I placed the stencils, the guns were all you could see."

"The two of them were clowning around, laughing the entire time, because for some reason Ashley was wearing a short dress with no underwear. So she spent most of the time trying to cover her ass while I tattooed her foot. It was pretty funny."

"Is there any place on y our body you wouldn't tattoo?" Bang Bang asks Delevingne. "Um... probably not my face. I've already done my ears, so anywhere... Hmm. Probably my face. I probably wouldn't do that. Or my vagina... probably..."
