Usher, who lost his grandma at 87 right before Christmas, took to his Instagram page to share pictures of the two of them.
The pictures showed her supportive of his career as they were spotted backstage right before his performance.
The post also contained a clip of the late evangelist leading the singer and his team in prayer before the show's start.
The star noted that it took him a few days to get used to the new reality of not having her with him anymore.
He stated part of him wanted to stay strong for others while the other part broke down silently.
The music artist described her as always being there for him and ready to pray for him through any storm he faced.
His peers and fans took to the comment section with messages of love and support for the grieving star.
The actor and his music executive girlfriend expanded their family and welcomed a son last year.
The newest addition made him a father-of-four as he took to his age to introduce his son to his followers.
