TMZ reports Evelyn thinks Chad has been cheating, so is now putting the red light on wedding plans.  Things haven’t been called completely off, reportedly, but it’s all now up in the air:

Chad Ochocinco’s famous fiancee has slammed the brakes on the couple’s wedding plans, TMZ has learned … all because she suspects the NFL star has been messing around behind her back.

“Basketball Wives” star Evelyn Lozada recently confronted Ocho after she became suspicious about his behavior … and she isn’t convinced he’s been faithful.

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.

Sounds like one (or both) of their camps are feeding smoke and mirrors to the media in hopes of intriguing a network to pick up and pay for their reality show.  Especially since Evelyn has been tweeting with Chad as she normally does, including pics of the two together (above), as recently as yesterday.

Time will tell….
