Mother of Terrell Owens Baby Still Wants To Get Paid

TMZ broke the story ... T.O's fourth baby mama -- a woman named Melanie Paige Smith -- filed papers earlier this month to BLOCK T.O.'s request to lower his massive child support payments.

In the docs, Smith's reasoning was largely based on the fact that T.O. had recently inked a deal with the Seattle Seahawks, for close to a $1,000,000 ... and could afford to continue shelling out for his kid.

But as of Sunday that's not longer the case -- Terrell revealed via Twitter that he was axed by the NFL team and is currently a free agent. Translation -- no more paycheck.
