Rapper Big Sean is in mourning following the death of his grandmother.

The Mercy hitmaker paid tribute to Mildred V. Leonard, who passed away on Friday (19Dec14), by posting a series of pictures and a touching message on how she helped support his dreams on Instagram.com on Tuesday (23Dec14).

In one message he writes, "My grandma passed away a couple days ago. I haven't said anything to anyone because honestly I feel like she's still here. I definitely can feel her consciousness. Im having a hard time accepting her death, but I must acknowledge my grandma's life, a true hero...

"She was the best grandma anyone could ever ask for... She put her heart and more into anything she was involved in. She gave as much as she could to her family and the world! She completely made something out of nothing...

"She supported me so much in every aspect and part of my life, even when I went against what was becoming traditional in our family, and didn't go to college to pursue music. She made a better life for me and the rest of my family, and I will forever be grateful I got to know and be loved by such an amazing woman! I'm so proud of her. She was truly a treasure to this world and everyone she came in contact with. She's the reason why I'm so passionate about giving back. Her spirit will live through her family. We miss and love u so much Grandma!"
