Stevie Nicks talks about her cocaine addiction

Photo by Adrian Sanchez-Gonzalez / Getty Stevie Nicks has some words of wisdom for rising starlets: Spend more time in a bikini. “I wouldn’t go out to the beach without a sarong from my neck to my ankles,” she tells Billboard of her younger years. “Now I see a picture of myself from that era in a bikini and I’m like, ‘You looked great. And you missed out on a lot of fun vacations, because you were so sure that you were fat.’ ” Now 66, the Fleetwood Mac singer admits times have changed, making it even harder to be a young woman in show business. “All the little girls in their 20s, they’re terrified of looking like they’re not 16. And I’m like, ‘Oh, just get ready for what’s to come.’ It’s going to be way harder for them. The world has become a much more vain place.” Nicks also discusses her cocaine abuse, which came to a head in the 80s when a doctor warned she’d have a brain hemorrhage if she did one more line. After that rude awakening – and being inspired to write “Mabel Normand” by the true story of a 1920s actress’s tragic drug addiction – she sought help in rehab. “Suicide was never my MO. I’m basically a happy person. I was a happy person back then. I just got addicted to coke, and that was a very bad drug for me,” she explains. “It was obviously a very bad drug for Mabel too. She had a gang of rich kids, like Lindsay Lohan today. That same bunch of girls comes around every 15 years.” As for whether she’ll ever write about her own fascinating life, Nicks says, “The world is not ready for my memoir, I guarantee you.”
