And now for the refreshing twist: That toilet-flush of innocence is not this woman’s whole story, nor, it turns out, the most interesting chapter. In four hard-won years of sobriety — and we’re talking the grinding, unglamorous work of it, the sober companions and living houses, the daily mindful avoidance of triggers — Demi Lovato has thrown herself deeply into a useful and engaged life. In the last year alone, she hit up Capitol Hill to advocate for the mentally ill, has been a vocal ally of the LGBT community, rallied the Latino vote, and stumped for Hillary Clinton at the Iowa caucuses. And with the release of her album Confident, she’s made a conscious decision to concentrate on music that showcases her vocal chops rather than slick, poppy hooks. In other words, she’s trusting and using her voice, which we may have underestimated all this time.
