50 Cent has reportedly neglected his eldest son since the birth of his new baby.
The rapper - whose real name is Curtis James Jackson III - has 17-year-old Marquise Jackson with ex-girlfriend Shaniqua Tompkins.
He also has 16-month-old son Sire Jackson with model Daphne Joy. 50 shared several photos of the baby on his Instagram account earlier this week before deleting them shortly after - the first time he had publically acknowledged the tot.
Since Sire was born Marquise is said to have been neglected by 50 and, according to TMZ, Shaniqua claims the last time the father and son saw each other was in May 2012. This was several months before the musician's second child was born.
The website also claims 50 hasn't even spoken to Marquise since their public argument in January 2013 via text messages.
It was a botched visitation attempt which triggered the row, with the rapper insisting he went to visit his son in Atlanta but wasn't welcomed inside the home.
He reportedly threatened to cut all ties with Marquise, telling him: "I don't have a son anymore".
50 also allegedly asked the teenager to take a DNA test to prove he is his biological son, suggesting Shaniqua had been unfaithful.
Despite these rumoured harsh words a representative of 50 insisted to TMZ the rapper is upset by the situation.
"50 is saddened by the attention-seeking tactics of his son's mother. He remains a proud and supportive father and feels blessed to have two sons," they said.
A source close to Shaniqua also claims she hasn't been employed since 2002 and that her statements are a "money grab" opportunity.
During 50 and Marquise's heated text exchange the youngster apparently insisted he wasn't interested in getting a fortune from his famous father after he didn't receive gifts for this birthday or at Christmas
"Well if u feel that way, I don't care about no gift it's the thought that means the most, remember this money ain't everything (sic)," read one message.
