Our hearts go out to Demi Lovato after the passing of her beloved grandfather.
The "Cool for the Summer" artist, whose album Confident is due out Oct. 16, posted an Instagram today in honor of her grandpa, asking her fans to keep her grandmother in their prayers during this hard time.
"My heart is absolutely broken and I can't even begin to imagine a world without my Papa but I know one day we'll meet again and that's what keeps me going," wrote the pop-rocker. "I hate writing this... But RIP Papa... I miss you so much already. I love you. Please keep my Mimaw in your prayers."
