From TMZ: Pittsburgh Steelers wide receiver Antonio Brown ran off with his child and is refusing to give the kid back to his mother … so says Antonio’s baby mama — but the NFL player claims she’s flat out LYING in a soulless scheme to make a quick buck.

Shameika Brailsford filed docs in Miami, claiming Antonio has had custody of their 4-year-old son in Pennsylvania for months, while he plays with the Steelers — and she’s worried to death he’s not being taken care of.

Shameika says 23-year-old Antonio took the child — also named Antonio — without her permission, and she hasn’t had contact with the kid since Antonio took him away.
