Rapper 50 Cent is mourning the loss of his beloved grandmother.

Belulah Jackson has passed away but the cause of her death has yet to be revealed, according to MTV News.

The In Da Club hitmaker openly spoke about his grandmother in the past, as she and her husband took the rapper in when he was eight years old following the death of his mother.

In June (14), the star, real name Curtis Jackson, told New York radio host Angie Martinez that his grandmother was suffering from an unidentified illness, and hoped she would pull through.

He said, "Her actually being sick, for me this is the only person who took care of me. It's really uncomfortable for me. If I had one person in the world that I could give everything that I have to and I'd be comfortable with it, it'll be my grandmother."
