EXCLUSIVE

NeNe Leakes and Kim Zolciak were thiiis close to reuniting on TV … but Bravo just scrapped their new show, "Road to Riches."

TMZ has learned NeNe and Kim’s road trip show -- think Oprah and Gayle with more arguing -- has been 86'd due to scheduling issues.

We’re told the 'Housewives' BFFs-turned-frenemies just couldn’t get on the same page. Kim is in the midst of shooting her show, "Don't Be Tardy" -- and NeNe is taping the ABC game show, "To Tell the Truth." ﻿
