News of their separation came as a shock to fans as Demi openly talked about the prospect of getting married to the That 70's Show actor. The Let It Go hitmaker also praised him for standing by her side through her struggles with depression and substance abuse. In 2015, when she celebrated three years of sobriety, Demi thanked Wilmer for keeping her alive. She wrote on social media: "After sharing my ups, putting up with my downs and supporting my recovery... he still never takes credit and I want the world to know how incredible his soul is. I really wouldn't be alive today without him. I love you Wilmer."
