Former LA Ink star Kat Von D celebrated six years clean and sober this weekend with a post on Instagram. “Today, marks my 6th year of sobriety! Yay for not being a drunken a**hole!! :)” she tweeted, with a photo of her holding up six fingers. The 31-year-old professional tattoo artist, whose celebrity clientele includes Lady Gaga and Beyonce, finally decided to get sober after her drinking started to threaten her work. “When I realized that drinking was getting in the way [of my tattoo’ing], I woke up one day and said I don’t want to drink anymore and I stopped,” she told Rosie O’Donnell last year. After quitting substances she realized, “My friends aren’t really my friends, I’m just a party favor.” But since getting sober, she hangs out with people who are “on the same frequency.” Von D has been romantically linked to several sober dudes, including Mötley Crüe bassist Nikki Sixx (who also recently celebrated a sober anniversary), and Jesse James, to whom she was briefly engaged in 2011. After James was accused of cheating on his ex-wife Sandra Bullock in 2010, Von D urged others to show compassion. “I think we’re all human and we’re all capable of making mistakes,” she said in his defense, “I think if I were to be crucified for my drug addiction three years ago now, it would be harder to live with that. I’m sober now, I’ve made mistakes too.”
