'Basketball Wives' Star Eric Williams -- Arrest Warrant Issued

"Basketball Wives" and former NBA star Eric Williams is about to learn a hard lesson -- babies can cost you your freedom.

A judge just issued an arrest warrant for Williams ... because he's completely blown off a paternity case which required him to both appear and submit a DNA sample.

As TMZ first reported, Williams -- who is in the process of divorcing "Wives" star Jennifer Williams -- was slapped with a paternity suit last year by a woman who claims he knocked her up.  The woman's son was born in October, 2011, while he was still living with Jennifer.

Williams has been pretending the case doesn't exist -- he hasn't even hired a lawyer. We're told he's ignored phone calls and texts from the baby mama.

Calls to Williams have not yet been returned. At least he's consistent.
