Demi Lovato Mourns the Loss of Her Great Grandmother with a Touching Tribute

Demi Lovato's emotional note about her great-grandmother's death will break your heart. After her beloved "Mimaw" passed away Sunday, the "Stone Cold" singer shared a tribute with fans about the impact she had on her life.

"This morning I lost my world and the world's most special woman," she wrote on Instagram Sunday. "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. I attribute my strength to her.. She held on when she lost the love of her life.. The one she was married to for 53 years. She smiled even though she lost a son just this year. She told everyone she loved them every single chance she got and she joked even when her strokes left her unable to speak properly."

Her great grandmother's death comes less than a year after the loss of her great grandfather, whom she referred to as "Papa." Lovato not only referenced him in her message, but also thanked fans for the support they had given her after she asked for prayers for "Mimaw" during the last few months.

She continued in the note, "The smile that she had not only could light up a whole room but it most definitely lit up the entire nursing home. 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. The pain I feel is almost unbearable but because of her strength I will power through it. The love and support I have received has been empowering and so special to me.. I love all of you so much and I am forever grateful for the prayers, texts and fan art my Lovatics have made me. Thank you."

"Mimaw, I hope you are with Papa now.. I hate that I can't hear your voice but I love that you are no longer in pain," she added. "I love you so much and I miss you more than anyone could ever imagine. I'll miss your smile, your wittiness, painting your nails and your kisses. I really do love you more. Rest in peace and most importantly rest in the Lord. #RIPMimaw."

Lovato went on to post a photo collage of "Mimaw" that included a shot of her great grandmother holding hands with "Papa." Days before "Mimaw" passed, Lovato also shared a shot of herself cuddling her in a hospital bed with the caption, "I love you Mimaw." She went on to encourage fans via Twitter to make the most of the time they have with their loved ones.

"Life is so short. Cherish every moment you have with your family and friends...I hate saying goodbye," she tweeted Friday. "But at least I get to say it."
