Amber Valletta started modeling at age 15, was on the cover of Vogue by age 18, and got sober by age 20. Now, at age 45, the supermodel is opening up about the drug and alcohol abuse in her youth, and how she thinks about her addiction struggles today. Valletta’s life and career have taken many turns, leading her into acting, building a family, and now, into climate activism and sustainable fashion. The model has a clear view of her past, present, and future — and her candor about even her hardest times is seriously inspiring.
