Rapper Future can call himself a rapper and a parent ... AT THE SAME DAMN TIME ... 'cause he just took a DNA test proving he's the father of a 10-year-old son ... TMZ has learned.
Future -- aka Nayvadius Cash -- was sued last year by Jessica Smith -- who claimed the rapper knocked her up in 2001 ... but should be ordered to pay her child support.
According to court docs filed in Georgia, the 29-year-old rapper took a DNA test -- which confirmed with 99.9% certainty the kid was his.
In light of the results, Future and his baby mama struck a deal ... he agreed to be legally recognized as the father, fork over $1,662 in child support per month and pay for the cost of the DNA test ($889).
The judge signed off on it, and the case was closed earlier this month.
FUN FACT: In the docs Future lists his monthly income as $16,516.30.
FUNNER FACT: At the beginning of Future's hit song, "Same Damn Time" ... Diddy insults all of his haters by calling them out on their inability to "multitask." How fun is that?!
