T.I. -- Iggy Azalea's Alleged Husband Is Frontin' ... She Shouldn't G

Hefe Wine wants to make a quick payday off Iggy Azalea ... but her boss T.I. doesn't think he should get one red cent.

Our photog caught up with T.I. outside Crustacean Monday night and asked what he thought about Wine producing a doctor who says he and Iggy were hitched ... and he thinks it's all about the green.

T.I. teased us a little ... saying "the truth" will eventually come out, and when it does, Wine's percentage will be a lot less than what he's hoping to get.

As for T.I. -- he says he's only focused on ONE thing.
