Warren Sapp's Ex-Wife -- You Still Owe Me $3 Million

Warren Sapp ain't out of his ex-wife's doghouse yet ... at least according to court docs which show the NFL legend has still not paid more than $3 million in back support ... TMZ Sports has learned.

Here's the deal ... Sapp filed for Chapter 7 bankruptcy back in 2012 ... and all of his many, many debts were made public.

One of those debts is owed to Jamiko Sapp ... the mother of two of his children ... who claimed Warren owed $3,104,207.20 in "domestic support obligations."

Well, according to new docs filed Monday in Florida bankruptcy court, Warren has only repaid $8,236.85 ... less than 1% of the debt.

Meanwhile, Sapp is still living pretty high on the hog ... making $100k bets with rappers and test-driving fancy cars.
