Kat Von D
Tattoo artist and reality star Kat Von D has been sober since 2007, when she realized that her drinking was affecting her tattooing. While on The Rosie Show, she shared: “I had made a promise to myself that if there was ever anything in the way of my ability to tattoo that I would cut it out. When I realized that drinking was getting in the way, I woke up one day and said I don’t want to drink anymore, and it stuck.”
