NeNe Leakes: Too Busy For ‘RHOA’

NeNe Leakes' streak on "The Real Housewives of Atlanta" is finally coming to an end ... at least based on what's NOT been going on during season 9 tapings.

TMZ has learned they've been shooting for weeks now, and NeNe is nowhere in sight.

It seemed like she was possibly coming back to the main cast after being named a guest last season. She's been busy with a HSN clothing line, one woman tour, new game show and a stint on "Fashion Police."

Our 'RHOA' sources tell us producers have added at least one new cast member, and NeNe -- the only remaining OG ATL housewife -- doesn't look to be part of plans going forward.

We're told "guest appearances" are always a possibility, but as of now producers aren't counting on having NeNe.

We suspect Kim Zolciak might have 2 little words for her ole frenemy ...
