Michael Jordan's alleged baby mama believes the proof is in the puddin' ... so she wants the former NBA star take a DNA test STAT ... to prove he's the father of her kid.
Pamela Smith filed new legal docs this week in her ongoing paternity suit with Jordan asking a judge to force the b-baller to pony up some fluids or hairs ... or skin -- this after Jordan recently denied fathering her son, Grant Taj Reynolds ... born back in 1996.
In the docs, Pamela says she KNOWS Jordan's the dad because they had sex approx. 9 months before Grant's birth -- something she claims Jordan's NEVER denied -- and genetic testing will prove it resulted in the pregnancy.
As TMZ previously reported ... Jordan filed docs of his own earlier this month, DENYING he's the baby daddy -- and claimed paternity for the teenager was established YEARS ago in a previous case.
A judge has yet to rule.
