— -- Demi Lovato took to Instagram Sunday night to write a heartfelt tribute to her great-grandmother who passed away.

The death of the 23-year-old singer's great-grandmother -- whom she called "Minaw" -- comes seven months after the death of her great-grandfather, whom she called "Papa."

"Mimaw, I hope you are with Papa now," Lovato shared with her 39.6 million Instagram followers. "I hate that I can't hear your voice but I love that you are no longer in pain," she wrote. "The pain I feel is almost unbearable but because of her strength I will power through it."

Calling her great-grandmother "the world's most special person," Lovato explained that they shared a close bond, and thanked her fans for their support.

"There is an emptiness in my heart that only her spirit can fill and I pray that I will feel her by my side every single day until we meet again. I attribute my strength to her," she wrote. "I am forever grateful for the prayers, texts and fan art my Lovatics have made me. Thank you."
