NBA's Stephen Jackson -- I'm Still Bangin' My Estranged Wife ... So Call Off Divorce!

If you're still intercourse'n ... there's no divorce'n -- so says ex-NBA star Stephen Jackson ... who's asking a judge to throw out his wife's divorce petition because they're still knockin' boots like a married couple.

It's one of the strangest legal docs we've ever seen ... Jackson says the judge should NOT grant his wife Renata a divorce because he believes she's just trying to score a prenup payout ... when in actuality, they're still very much a couple.

FYI -- Jackson says Renata's payout under the prenup is based on his net worth at the time she filed for divorce in 2013 ... and since he was still playing in the NBA at the time, the payout would be significantly larger.

But in new docs filed in state court in Georgia, Jackson says he can prove his marriage wasn't dead then ... and it isn't dead now ... because he's still banging his wife on the regular.

In fact, Stephen says he often still takes her on fancy vacations to places like the Bahamas, Cancun and Jamaica ... and presumably bangs her there too.

Which leads to this explanation Stephen included in new court docs -- "Despite filing for divorce, [Renata] continued her relationship with [Stephen] in an effort to 'have her cake and eat it, too.'"

We can't imagine this case is going to have a happy ending for Jackson -- because if he gets his wish, he's still gonna have a pissed off wife on his hands. And if he loses, he's gonna have to cut a big, fat check.
