Terrell Owens
can easily afford $5,000 a month in child support thanks to his brand new NFL contract — this according to one of his baby mamas … who”s now fighting T.O.”s request to reduce his financial obligations.

Owens had filed legal docs last year — asking to reduce his enormous child support payments to FOUR separate baby mamas — because was unemployed at the time … and seriously strapped for cash.

But last week, Owens signed a contract with the Seattle Seahawks — a deal reportedly worth almost $1,000,000.

Which is why baby mama #4 — a woman named Melanie Paige Smith — has just filed papers, asking the judge to dismiss T.O.”s payment reduction request.

In the docs — filed by Melanie”s lawyer Randall Kessler — she claims, “It is clear that a downward modification of [T.O.”s] child support obligation is not warranted” due to his new Seahawks contract … as well as his income over the last 5 years, which Melanie estimates to be around $29,000,000.
