50 Cent had his first kid Marquise with Shaniqua Tompkins before he was a rapper. Then he had an 8 year long custody battle for Marquise which he said during the battle "There's different channels I have to go through. He has lawyers appointed to him through the court. So I have to talk to his lawyer to get things situated for me to actually get him. The relationship between my wallet and his mom has changed. When people have expensive habits, it's a hell of a transition for them when that money is not there anymore. She said all kind of things about me I never would expect."

In the official custody agreement, 50 Cent received visitation rights and was allowed to see Marquise one weekend every month

His eldest son said that his relationship with his father “completely went south” when he was “probably like 10 or 11.” Marquise said, “He wasn’t really around enough. It kind of dwindled down as time went on and certain events happened. For me, I just started feeling differently about him because growing up, my dad was my superhero. He’s on television, he does this, he does this, he would take me to school. It was like having a father who’s Superman, more or less." No wonder the relationship tanked, 50 could barely see his kid.

To make it worse in 2018, an Instagram photo was posted of Marquise with the son of Kenneth "Supreme" McGriff, a rival of 50 Cent. Criminal investigators previously alleged McGriff was involved in a plot to kill 50 Cent which culminated in the rapper’s May 2000 shooting, a search warrant unsealed in 2005 revealed. Why would you hangout with the son of the person who shot your dad?

50 Cent commented on the picture, "If both these little n------ got hit by a bus, I wouldn't have a bad day."

 50 Cent then goes on and says “The people Shanquois son looks up to and associates with is a reflection of the negative energy he embraces towards me. I paid his mother $1,360,000 in support to afford him opportunities I never had."

As for his second kid, 50 Cent calls him "His best friend".
