50 Cent is mourning the loss of his grandfather, Curtis Jackson Sr.

The G-Unit leader took to his Instagram page to announce the tragic news on Wednesday (July 31). “You do know none of this shit really matters, [winking emoji] we can’t take it with us. I lost my Grandfather last night, now he can go everywhere with me,” he wrote.

In a follow-up post on Thursday (August 1), 50 Cent shared a heartfelt tribute alongside photos of the pair over the years. “My old man is [a] tuff act to follow, he sacrificed for all of us. He made me smile every time I saw him. The Last time he went to the hospital he was dehydrated so the nurse couldn’t find a vein. I came in, I said pop you alright?” he recalled. “He said no [confused face emoji], she stick me again and I’m a start shooting. LOL [laughing emoji] I almost fell out! [three laughing and crying emojis] South Side we out side WTF!” he wrote.

The cause of Curtis’ death has yet to be revealed. He was 91 years old. During an interview last year, 50 Cent revealed that his grandfather raised him. “I grew up with my grandparents. We were living on my grandfather’s income. He was real old-fashioned. He is a representation of tradition for me,” he said. “He would come [home] and give my grandmother his check, and I never understood that growing up […] Later, as an adult, he said, ‘You couldn’t see it and you won’t understand it ’cause you were a baby, but I gave your mama the check to stop her from looking at things I couldn’t give her.'”

The Queens native continued, “If you understand where you’re at financially, you make logical decisions versus if you didn’t have an understanding because he was handling things, then you could feel deprived. It could feel like there’s something else out there that you’re not experiencing.”
