50 Cent may be entertaining the masses on Instagram with his relentless quest to get back money he is owed but joking about his family is not something he is interested in.

Over the weekend, on Friday (June 28), a situation unfolded that further showcases that while 50 Cent and the relationship he has with his oldest son Marquise has been strained over the years, it’s far from being water under the bridge.

During the performance, which took place at Brooklyn’s Barclays Center and featured appearances from Cam’Ron, The Lox, Fabolous, DMX, T.I., Snoop Dogg and others, 50 Cent’s son was in attendance, sharing footage of the experience on Instagram and seemingly enjoying his father’s set.

However, things took a sour turn when a fan called out Fif for not hooking up his son with a backstage pass for the concert. A fan questioned 50 about why his son was not in a VIP section and was among “regular” attendees.

“Negro why you didn’t give your own son backstage passes he in the crowd like regular people smfh,” the person wrote.

50 got wind of the comment and shot back, “I got a blood test that’s not my kid f–k outta here.”

While the comment has since been deleted, it was brought to Marquise’s attention. The 21-year-old decided to respond, posting a GIF of Maury Povich on his Instagram Story. The GIF shows the talkshow host, who is known for settling paternity issues on television, nodding with a crying laughing emoji in the center.

Over the years, Marquise has claimed that 50 Cent wasn’t there for him at times during his youth, with the pair’s disputes making various headlines over the years. Hopefully the two are just enjoying cracking jokes online and the situation doesn’t continue to escalate.
