Not long after losing her puppy in a horrible accident, singer Demi Lovato is grieving once again with the loss of her great-grandfather, whose death she announced to her fans on Sept. 29 on Instagram.

The "Confident" singer shared a photo on Instagram of her great-grandfather with her dog Buddy, who passed in July, and expressed her sadness over the loss of her loved one.

"My two favorite Buddy's are now playing in Heaven. 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. I hate writing this... But RIP Papa... I miss you so much already. I love you. Please keep my Mimaw in your prayers," the singer wrote.
