Soulja Boy is not the father of his ex-girlfriend’s son, a paternity test proved earlier this month.

According to TMZ, the Atlanta native took the test Sept. 4, close to a year after the child’s mother, Diamond Shantaniece Mackey (not to be confused with his other ex, rapper Diamond), filed a paternity suit against him. 

Mackey revealed an old photo of her straddling SB to prove that they were once involved. She maintained that he was one of two people she slept with prior to conceiving son Portlon. The second man was of mixed race, and therefore absolved because the child is not multi-racial, she said. 

As for SB, sources close to the rapper say that he feels bad for Portlon, who still doesn’t know his father’s identity. He’s also upset with Mackey for pegging him as a deadbeat dad before he even took the test. She reportedly told a welfare office that he fathered the boy.

SB’s paternity results state, “The alleged father lacks the genetic markers that must be contributed to the child by the father. The probability of paternity is 0%.”
