50 Cent allegedly abused his 16-year-old son in a string of profanity-filled text messages, it has been claimed.
According to RadarOnline.com, the rapper turned businessman called his son Marquise a "sh*thead", "motherf***er" and "f***ing stupid" during the hour-long exchange.
50 Cent, whose real name is Curtis Jackson, is said to have become angry when his son refused to open the door to him during a custodial visit.
Throughout their conversation the 38-year-old demands proof that he is his son and tells the youngster to "f*** you stop texting me" and "delete my number".
As his rage mounted he allegedly wrote: "I need a blood test cause that d*** sucking b***h you call mom was f***ing the hole time [sic].
"I don't have a son any more."
RadarOnline claimed the texts had been verified and that the phone number was registered to G-Unit Touring, the record label created and owned by 50 Cent.
The hip-hop star and Marquise's mother, Shaniqua Tompkins, are embroiled in a bitter custody battle over the boy.
Earlier this year, he issued with a cease and desist order to prevent her appearing on Starter Wives. He took the legal action allegedly out of fear that she would tell all about their relationship.
The leaked texts emerged just days after the star was arrested on domestic violence and vandalism charges following an alleged row with ex-girlfriend, Daphne Joy.
He is accused of attacking the former model - who is mother to his other child-and smashing up her apartment.
