Demi Lovato has penned a heartfelt tribute to her great-grandmother, who passed away this morning.

The "Confident" singer shared a moving, black-and-white photo showing her laying side-by-side with her "Mimaw," who had suffered from strokes.

"This morning I lost my world and the world's most special woman," the pop star captioned the image on Instagram. "I miss her more than words can even describe. 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."

The 23-year-old attributed her strength to her Mimaw, praising her ability to hold on and keep smiling, even after the death of Lovato’s grandfather, last year, then her Uncle Jeff’s passing in January.

"The smile that she had not only could light up a whole room but it most definitely lit up the entire nursing home," continued Lovato. "She was my great-grandmother but we were so close that I never knew it was possible that anyone could have the bond that we shared even 70 years a part."
