50 Cent's Son Has Biting Reply to Child Support Countdown Awkward By Evann Gastaldo, Newser Staff Posted Sep 16, 2016 12:02 PM CDT 14 comments Comments Curtis "50 Cent" Jackson performs at Starz's "Power" season two premiere at Best Buy Theater on Tuesday, June 2, 2015, in New York, (Photo by Charles Sykes/Invision for STARZ Entertainment/AP Images) (Newser) – In what one might call an ill-advised move, 50 Cent posted a picture to Instagram showing a countdown to the day—Oct. 13, 2017—he no longer has to pay child support for his oldest son, Marquise Jackson. "Man real life is gonna start Sooner then you think. Sad part is I wish you well, good. #Shanquagetsajob," the rapper posted, a (misspelled) reference to Marquise's mother, Shaniqua Tompkins. Marquise himself responded to the now-deleted post, the New York Daily News reports: "Don't worry I'll make you proud! Just don't forget to tell me happy birthday that day cause u missed a few," the 18-year-old wrote. Tompkins also replied to 50 Cent's Instagram post, calling him out for, among other things, not being able to spell, Perez Hilton reports. The relationship between 50 Cent and his son has long been strained; recently, the caption of a picture of Marquise Jackson at the premiere of a film he's in, Dope Fiend, referred to him as "50 Cent's son." The rapper commented on the image with, "His name is Marquise, take 50cent's son out your post please ... I have nothing to do with this project."
