In her first post on Twitter since releasing “Sober,” the 25-year-old singer shared a video of an emotional performance of the song — in which she reveals she broke her sobriety and apologizes to her parents and fans. In the footage, Lovato appeared to fight back tears as the crowd in Lisbon, Portugal, sang along and lit up the arena with their phones. “Tonight I took the stage, a new person with a new life,” she captioned the post. “Thank you to everyone who has supported me throughout this journey. It will never be forgotten.” Demi Lovato Returns to the Stage After Revealing Relapse: ‘Life Is Really Funny Sometimes’ Lovato released the song on Wednesday, then was back onstage Thursday night in Barcelona, Spain, for the latest stop on her acclaimed Tell Me You Love Me World Tour. The tune didn’t make it into Lovato’s set on Thursday, according to fans online. But video captured and shared to Entertainment Tonight showed that Lovato did get philosophical about life at one point. “Life is really, really funny sometimes,” the pop star said. “It can be difficult, but, for the most part, if you do what makes you happy and set yourself free, you’ll live an amazing life.” Pedro Fiúza/NurPhoto/Getty Demi Lovato Reveals She Relapsed After Six Years in New Song ‘Sober’: ‘I’m Only Human’ In “Sober,” Lovato sings about the guilt she feels about relapsing, asking for forgiveness from her family and from her fans. “Mama, I’m so sorry I’m not sober anymore / And daddy please forgive me for the drinks spilled on the floor,” she sings 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.” “I’m sorry that I’m here again,” she adds at the end. “I promise I’ll get help / It wasn’t my intention / I’m sorry to myself.” Lovato has battled addiction, mental illness and disordered eating for years. In 2011, she entered treatment, where she was treated for bipolar disorder, bulimia, self-harm and addiction. She relapsed after she left the treatment center, then entered a sober living facility for a year.
