Last March, Lovato revealed shecelebrated six years of sobriety,but in June she released a new song, “Sober,” on which sherevealed that she had relapsed.

“Mama, I’m so sorry I’m not sober anymore / And daddy please forgive me for the drinks spilled on the floor,” she sang on the heartbreaking piano ballad. “And I’m sorry for the fans I lost who watched me fall again / I wanna be a role model, but I’m only human.”

At the end of the track, Lovato sings: “I’m sorry that I’m here again / I promise I’ll get help / It wasn’t my intention / I’m sorry to myself.”
