RICK ROSS SAYS HE'S NOT THE BABY DADDY!

Rick Ross is adamant ... he didn't father a 3-year-old boy in Georgia to a destitute woman -- despite a recent paternity suit filed against the rapper -- and now, he wants to prove it ... with a DNA test.

The paternity suit was filed in Broward County by Florida Department of Revenue -- on behalf of 36-year-old Tyrisha Childers, who claims Ross knocked her up a few years ago ... and still hasn't paid a dime of child support.

According to the docs, Childers needs all the help she can get -- with zero income apart from $694 a month in disability payments. Worse, Childers claims she has absolutely no money in the bank.

But Ross filed his own response soon after -- claiming he never even slept with Childers ... let alone got her pregnant ... and he wants to prove it with a DNA test.

Sounds like some Maury sh!t! Lol!
