Chad Ochocinco's Marriage To Basketball Wives Star In Doubt?

Sources tell us ... "Basketball Wives" star Evelyn Lozada recently confronted Ocho after she became suspicious about his behavior ... and she isn't convinced he's been faithful.

The two are set to be married in the summer -- and while Evelyn hasn't "officially" cancelled the wedding yet, we're thinkin' the priest should start making other plans.

Plus, Chad and Evelyn were supposed to begin shooting their new reality show in just three weeks ... we're told that plan is also up in the air.
