50 Cent son's Marquise got on the wrong side of Twitter when he complained that the $6700 a month Fif paid his mother Shaniqua Tompkins for child support wasn't enough for him to live the life he wanted to live.

Marquise, who's 25 now, responded to all of that by making an offer to his dad.

He'll pay the famous rapper to hang out with him.

"Since y'all think $6,700 is sooo much money someone tell my pops I will pay him $6,700 for just 24hurs of his time so we can do everything I ever to do with him as a kid.  Red Yellow Green whatever color he like," Marquise typed.

It's 50's move now.
